My vin starts with "M50CA7J", which according to the charts means...

M5 = M500
0 = motorhome
C = 10001-14000lbs
A = 440-3 engine
7 = 1977
J = Tecumseh Road Truck Plant

While updating my 2 M500 brake pages I was only able to locate one P/N for the rear brake adjust screw. What I do not know is if the same adjustment screw is used on both sides or if there is a left-hand and right-hand thread difference for the M500 chassis. Can anybody answer this for me?

I saw them on Napa's website. I just forgot how I looked them up. Gotta try different year/combo till you find it. NAPA pretty much still carries most of the stuff but it can be a chore to look it up. Don't expect the counter guys to do it for sure.
I was able to get a hardware kit for mine.

I have the same issue on my 1975 Travco and am wondering if that "Rock Auto" link has the correct part # in to for a replacement booster?

I did a thread on it. Rockauto had a booster that "works" cheap. It was the correct one except the rear mount was different. I swapped the back covers. 2 years , still working good.

Ok so the most critical question I have is how do I confirm if I have the M400 or the M500 Chasis?

I have a 1975 Dodge Travco

If your vin starts with M5 it is an m500. M4 would be the M400. Most of the 270s and Mahals were the M500. I have seen pictures of the 320 on the M500 and M600.

What model ? If it's a 270 then it's an M500 most likely.
