Re: '72 C3500 GMC flatbed project

Donor truck is finally completely broken down. This weekend I will be sandblasting and painting all the bracket and starting to break down the C3500.

I have also discovered something interesting. The front spring hangers from the V3500 are, in fact, swappable - meaning I can install the left on the right. This lines up with the original frame mounts on the '72 perfectly.

I've also found that the rear spring hangars match up with one pair of holes on the '72, so I have good reference points at both ends to set my suspension from.

Other than that, I'm also working on installing the '87 Hydroboost setup on the '72 - based on some comparison today, I should be able to modify the hydroboost base plate to mount directly to the firewall in the '72, which is excellent news. I will have to either modify the pedal or the pushrod, though, as the hydroboost pushrod is some 2-3" shorter. We shall see but I suspect I'll modify the pushrod, the geometry for the pedal doesn't lend itself to modifying the connection point.

I promise to have some pictures soon!
