have you looked at 'Auto Mann' ?   jojo

Not familiar with that, I will look. Thank you.

My 1978 DM 800 has a Spicer F6.5-5-43 u-joint that I can’t seem to find. Is there a suitable alternative?

There is a listing on FB marketplace in Deltas NJ that says NOS DM hood and grill. I don’t know if DM600 or 800. $900. Worth a look. Mike 

Thank you!

Before you buy anything or tear everything apart , take the supply line off the control valve and put some air tool oil in it . Then turn wipers on and off a lot , keep putting them in park , if truck has been sitting  for a while , might be enough to solve your problem . 

In case you didn't know , park position is important . If your wiper control is pull out and turn to the right to increase speed , the park is... push in all the way till wipers go back to the bottom . If you turn the wiper control to the right to turn it on and increase speed , turn to the left all the way till wipers go back to the bottom . When they are in park, no air should go to the motor and therefore no air leaking out the exhaust . 

Just my thought anyway 

 

 

Thank you very much sir. I will do this.

No it's not. Air exhaust out of it when the wipers are on. 

 

Thank you sir. I will investigate.

So does the bottom port in the pic ( the one with the compression nut) not supposed to be hooked to anything?

The wipers come on sporadically for no reason and I was told that parking break doesn’t work. When you shut off the truck you can hear air leaking and I tracked it down to hear. I’m confused.

Would anyone be able to tell me where the airline that’s supposed to be in the empty port goes to? I really appreciate the help.

I live in Northern Indiana.

I need the DM 800 hood, breather cap, grille bezel that says MACK, and 5 hood grille bars. I couldn’t possibly afford to buy a whole parts truck not to mention having it hauled.

I live in Northern Indiana.

Can you please tell me what the grease fittings on either side of the grille are for? Also you will notice the gap between the body and the bumper on the left is greater than on the left. Do I need a new mount on the left?

How much we talking?

I also need an air filter housing cap as well.

I need a steel hood and the Mack grille bezel and the bulldog hood ornament.

Is there a usual culprit when it comes to the parking brake not working? Thanks in advance!

I just bought a 1978 DM867st1414. It has the Cummins 350 big cam. I don’t know what filter numbers to buy. Help would be awesome.

Thank you!

Is there a different model designation for the steel hood vs the fiberglass tilt?
