Yep There’s really no way to set a price on NOS ,, just depends on how much you need it . I’ve been fortunate with several things on the LJ and LTH,, I bought stuff from 3 or 4 different people and they always treated me fair,, They know I’m going to use it and not resell, and I’m the same way, I have given a lot of parts away knowing that they are going to use it on a project. 

That Steering wheel is actually “Brand New “ ,, There was a fellow down in South Carolina who was a “True LJ Guy “ , I talked to him in the mid 80s about some parts when I first started thinking of restoring mine, I never met him, or bought anything. He passed away later and I guess his family had a auction, a friend of mine went and bought some stuff, this steering wheel was in the new box , he kept it for years along with NOS Speedo and gauges . He sold his LJ . So he didn’t need them,,, Many Thanks to him for selling it all to me. 

I’ll keep my eyes open for one,, I have seen couple on FB Marketplace, a friend of mine bought one just like that down in East South Carolina for $2000 I took my Western Star to get it, I slid my 5th wheel back to keep it off my mud flaps ,, i think they would be fine with a single axle B . 

Yes it was exiting for both of us! Yes the oil filter is easy to service, the 750 on the left at the firewall isn’t bad either, I remember setting on the fender and changing it.  Mine has that same QR valve on the frame for steer brakes, thanks for the pictures 

The block looks great! All that will be nice on that 220 ,,, You want have those streaks down each side from those heads dancing around on a worn top deck ,, it will all be worth it. 

I agree on these old parts,, I put a regulator on my hose and set it at 100 for checking this system,, 

Agreed, I’m going to focus on steer axle brakes for now, I have shop air hooked to it so I’m going to check some pressures . 

Your correct, I’m sure it would work just fine, I was trying to use as many original parts as possible, but I’m not going to spend a lot of time and money when parts like your talking about are more dependable and available. 

That’s the way I’m going to hook it up and try it, I might still have to replace/ repair the relay valve that’s plugged now. I’ll eventually get it back to normal. Thanks again! 

Many thanks for all the replies, I’ll hook it up the way We All think it should be and find out what is leaking, and make repairs. OH how I wish that’s all I have to do before finishing it ! I’ve been putting the floor panels in today. 

I put both pictures on in order , hopefully my explanation will make sense, That line that loops around to rear of shuttle is from trolley , line going straight in is from treadle in second picture 

Ok , I took about a hour yesterday double checking the brake plumbing, Mechohaulic is  totally correct!  There is a quick release valve inside the left frame rail of this truck and both parts trucks, air goes from treadle to dash limit valve to top of this valve, each bottom port to right & left steering brakes ( so next I will have to hook a gauge up for them being slow) . So the first valve pictured is in the system has something to do with trailer brakes. I’m not sure if the “tee “ in the second picture is factory. Air comes from one delivery port on treadle to shuttle ( or double check valve) on the front side, the delivery from the trolley loops around to back port of shuttle valve. So when brakes are applied or treadle is pulled air comes out center port where the tee is , one line goes to service side of tractor protection, the other goes to left bottom port of the relay/ quick release valve with constant air to top port and right bottom port plugged . ( first valve pictured) . Since the first pictured valve has constant air, maybe it is a relay valve, air coming from delivery port at shuttle ( remove tee) to left bottom port, remove plug and run line to service of TPV ???  Maybe it had this relay valve in the system to give a extra boost of air to trailer service??? 

Thanks for the guidance, both the parts LJs has some sort of relay valve on the frame going to front brakes, and I couldn’t find a shuttle valve on them either. I’ll double check the plumbing and put a gauge on the front , the copper plumping is 100% original , ( I replaced a few pieces because they had bad rubbed spots) I think there was too many hands involved in the 70s , possibly taking a piece of copper off and plugging something. 

I did send 2 different pictures, the first is what we think is a relay valve , the second is a shuttle valve, the line goes from the shuttle valve to the bottom of the relay valve, I’m still thinking a line should be on the right bottom of the relay , just trying to find where the other end would have been. I’m thinking that maybe why the front brakes are very slow applying . Both my parts LJs are 48s and this is a 51 , The LT is a 55 . And they’re all different! I’m not sure when exhaust brakes came out, this one never had on according to the build sheet and the older drivers I talked to that drove it.  So if I see a LJ setting at a truck stop I’m crawling under it,,, Yeah that will be the day I’ll play the LOTTERY 

I think you’re correct,, I haven’t had time to play with it today, That truck had about a 7 year period from the time the Welding Company traded it in to Peterbilt ( that’s when my friend bought it) until I started driving it ,and I knew some of the guys that worked for him ,,, So there is no telling what  they may have bypassed if it had a leak, I always remember the brakes weren’t that good,, but all the old H ‘s and B’s weren’t ether. 

I’m not sure, I plugged the bottom line to it and the rear brakes worked normal, no leaks anywhere now, but the front is very slow, all lines under are copper and look original? 

It was a factory tractor, both parts trucks have that same dial style front brake valve, put the older LJ (48 I think) doesn’t have a tractor protection valve, it has 2 ball valves that the trailer airlines hook to,, the other LJ has the same tractor protection valve,,, I’m going to get under it and make sure that “Relay “ valve isn’t in a different location ,, I’m now guessing maybe someone put the tee in going to tractor protection and plugged that right port ,, ?? Thanks for advice! 

Yea I thought of that also, I traced  the lines from foot pedal up to dash to limiting valve ( dail type) back to that check valve where the tee is to this valve. But you may be on the right track, that valve could have been plugged years ago, and just started leaking when I put air to it for the first time in 30 years. I was surprised that the foot valve and had valve were not leaking. 

I dug through an old LJT manual this morning,, you’re probably correct, it talks of a relay valve but no picture. I have been the only one working/ using this truck for 45 years, and I never remember taking a line off, ( were the plug is ) the bottom line comes from a check valve that connects to the foot pedal and goes to front brakes , there is a tee off it before it gets to this valve the goes to service side of the tractor protection valve. ( top full air ) Relay valve in that location makes sense,, but it serves no purpose without another line??? I’ll keep looking for a better diagram . Thanks for all the advice! Hopefully someone can rattle my memory.
