Autocar

Parts were pretty generic back in that era. Might have problems finding Autocar specific stuff though since they have been out of production for a long time (ie no dealers). Even parts for my 1980 KW are hard enough to get through the KW dealer.

 

Wiper motors can be rebuilt, they still do that. Heater motors can be found and so can heater cores.

It is amazing what it sitting on the shelf of some of these companies that never turn over their old inventory. AND it is equally amazing when you get into these little clique groups who own these trucks what they know about the parts and where they can be found.

By the way, we have a company that runs Autocars up north of me, I see them when I head into the Detroit area all the time.

 

The latter 80's models here had factory tilt hoods. I doubt converting one would be worth the effort.
You know AutoCar was the heavy duty division of White. The White/GMC and AutoCar in those years had many interchangeable parts. The problem I run into now is the Volvo dealer can't or won't even try to look up parts for me.
Those butterfly hood beast with a Cummins were pretty tough. Did not normally spend to much time under the hood anyway. When you do it could cause a preacher to cuss at times.

 

They were pretty much volvos or should I say white/gmc's in the late 80's with a different grill. So parts aren't hard to come by.

 

I had a B model Mack, a International Paystar and a Autocar all with butterfly hoods and all were dump trucks, they are horrible to do routine maintenance on, you either have to lay on the fender or kneel on the fenders.
If you are looking for a mid 80's or later tandem dump truck buy a Mack, i have had several of them and with the right specs nothing out there is better off road.
