Technical model a truck vs car frame

The AA frames are not the same they are completely different. The rear springs mount fore and aft instead of transverse.

 

Exactly.

 

You redirected me to this very post.

 

N/m I figured it out

 

some frames have the steering box holes on both sides.....

 

Thanks,can frame be changed and used by adding rear crossmember?

 

The frame is double the size and weight of a standard A frame. For the little price of an original A frame just find one and save all the h***le.

 

The reason I asked is these says you see the big trucks parted out to build small trucks and wondered if stock ch***is was useable in conversion.

 

There are of course two AA frames, '28-9 and '30-31, with plenty of differences. Don't know much more about them...
They have some attractions. Both are stouter than A without being ridiculously large, they follow the right general shape to take bodies, and once cut to length you can have a full-length frame allowing easy use of either A or V8 type springs by adding a crossmember and also giving frame support all the way back of your body or bed. I think they might well be a good platform for a rod.

 

If my coupe had solid subrails I would set it on the early 30 AA ch***is and show what to expect for modifications later this week. If I get all of the welded on farmer modes off of it later this month, I may be able to help with your decsesion. There was a guy in Omaha who put his roadster on a AA ch***is, but I never seen much for details on what he had to do and what the outcome was. Rod
