Yeah, dropping the entire suspension sounds like a really cool idea!
However Bob, in your case I imagine you actually need to roll (flat-bed etc) the chassis over to the paint shop eventually, so the suspension would eventually need to be re-attached to the car... UNLESS, you happen to have a complete suspension with wheels lying around to swap in-and-out....
Now that I think about it, is the car safe to roll with the suspension (without engine) attached to the chassis through a pair of subframe mounts only? In other words, is the torsion bar adequate enough to prevent the subframe mounts from having any longitudinal flexion? (I hope you keep the torsion bar and steering still connected)
I guess this might be ok since the car would move relatively slowly... but while you're there Bob, you might want to make sure you've got good subframe mounts (especially since the painter might end up raising the car, and dangling the front suspension)
ok, this cook is leaving the kitchen now.... looking forward to the next installment of your most excellent project!
