I just recently got a 77 w200. Was running real rough so brought it in and they said the brake booster is leaking. Been trying to find a replacement. But cant seem to find anything that can help. I know it is a 3500lbs. I find a few 4500. Just wondering if anyone knows the specific info and a place to find one from.

 

Try your local Napa Store...

 

That's the funny part. Tried them we found a part they had. And a part number but they are unable to order it. Think I found it on rock auto. But we will see when it comes in.

 

These guys have helped me out on a few projects... lol

Just in case...

 

I get quite a few parts from rock auto. I have even found parts for dads 37 dodge truck there.
