This weekend I was able to finally "tack" the hinges in place and make sure the cab tilted with the bumper on and did not have any binding/clearance issues after lowering the cab. Big win ! I will probably need to move the bumper up a bit when it's finally assembled. I also got the front torque rod adjusted so the rear axles are better oriented and the center drive shaft fits right. -

Agreed. It didn't "smell right" to me. I've been trying to find a 1:1 photo of an Astro 95 with a Hendrickson suspension to try to see angle of the axles and the torque rods, but I haven't been able to find any yet. -

I think the rear torque arm is probably OK ? I would expect the rear axle to be "canted" back a bit like it is to make the drive line between the front and rear axle more of a straight line. -

This weekend I finally got the rear suspension and axles "tacked" in. The molding of the Hendrickson beams and the axles is not great -- loads of "slop" all over the place with these. To try to tighten things up, I had a buddy help me and we drilled the beams and then installed pins through the axle brackets and beams (like the real 1:1 suspension had). Still some "tweaks" to do, but it's progress. It also looks like the front torque rod is a bit long. The forward axle is too "flat" and that makes the inner drive shaft between the axles not long enough. So some correction to do there too I think. -

Worked a bit more on the fit of the crossover pipe today and test fit radiator with engine in. Finally attached the fan support bracket to the block! Was sweating that one as it needed to land the fan in the center of the fan shroud. -

After the cab was lowered, I wanted to check to see that there were no clearance issues with the interior tub in. OK -- it clears. Just ! Man that's close ! -

I got the cab supports lowered. Here are before and after photos. It seems about right now based on 1:1 photos. -

Slowly getting all the frame stuff on the right side mocked up before I start lowering the cab -- to make sure there aren't clearance issues with anything. -

Well now the next chore. Of course, the cab sits waaaaaaaaaaay too high on this kit. Looks like it needs to be lowered about 1/8" or 3/16" to sit correctly. Based on 1:1 photos, the bottom of that cab step should be about level with the top of the front tire. -

Thanks ! My next quandry -- for the single exhaust, I'm guessing the tabs on the exhaust need to be removed ?? And just attach the exhaust to the air intake pipe using the tabs on it ? The instructions don't show the tabs on the exhaust (parts 228 and 229). -
