Hi, I have a 1958 B67T Mack with a 36" sleeper on it, there's a hole in the roof already, from what looks like was probably a roof unit it once had. I started looking for roof units, because I want to put air back in the truck (I live in Florida) and I came across Dometic 12 and 24 volt self contained units. I am familiar with the company because I helped my friend put one of their units on his Airstream, and it works great! HAs anyone had any experience with their 12/24 volt systems? It would make installing air so much easier if they work good. The website say's they are available all the way up to 13,000 BTU ! I would imagine that little Mack cab and 36" sleeper would turn into a freezer with a 13000 BTU unit! lol

Maddog, do you think the non turbo 673 will pull a higher gear empty, or with just one car behind, or on it? I just want to be able to cruise 74-75 MPH.

Thanks

Thanks everyone, and Freightrain, the guy with the 9.50 gears must have NEVER left the jobsite! Lol. Yeah, I have been wanting an old A-Car, KW, PETE, Brockway, or B Model Mack forever, (an LT is just a dream! lol) just because I remember riding in them when I was a kid with my dad and uncles, I had a 71 361 Brock back in 84-85, it had a 1974T cat that was turned up and had enough torque to move a mountain, it had 4.11's and a 13 double over, I loved that truck, it was black with chrome Farr air cleaner, bumper, grille, and chrome straight 6" stacks, wish I had it now, back then I didn't think it was all that old though! lol

Yeah, I was thinking the same thing

No, I haven't driven it yet, he drove the truck down from Gainesville area, about a two hour drive, and said it did 55

Yeah, me neither, that's what the guy told me, maybe it just actually had the trans swapped, I'll have to het the numbers off it

Not sure what you're looking for, but I just got a "58" B67T with a sleeper box,and a 18-20 foot tilt bed, runs good with a END673 and a duplex trans, it is a single axle

Hi, I live in Florida, so all flat land, all I will haul with the truck is one car 90% of the time, the rest of the time I will be empty, and once in a great while I may have two cars on it, the shift pattern diagram plaque in the truck shows the ten speed direct shift pattern, but the guy I got it from told me that top gear has been turned around, so that 5th gear is up against the dash. So I don't know if that would make it the same as the 9 speed OD or not, I'll have to go get the numbers off the trans and rear, I was just curious what gears are available, and whet the interchangeability scenarios is? But I guess if later model "R" model diffs are the same (bolt in) that will help a lot, it is a front loading diff buy the way

Thanks

Hi, I recently purchased a 1958 B67T, it is a very solid truck, has a sleeper, and an 18-20' tilt bed on it, it was used to haul a race car, the problem is, it is only geared for 55 MPH !! It has a duplex, and fifth gear has been turned around, to make it an overdrive (at least that what the guy told me, and so far every thing else he has told me has been true. I just haven't been able to take it down the road yet! I am trying to find out what kind of ratios are available for this truck, or if the newer single axle differentials will interchange, or am I going to have to put a whole rear end out of a later model truck? I will go insane if I have to make a long haul to get a car or two and can't go over 55 MPH !! Lol !! Help !! I would trade it also, for another old Mack,Brockway, or Autocar, that is already geared for the highway, and maybe has a flatbed, or is long enough for one, if not, a short one will work, because I have a 20' car trailer.

Thanks

Keith
