I have Kevin's Hunt version of this car, and it's one I am excited to do at some point soon, so I'll be watching to see what you do here. I'm planning to scratch-build the suspension, so looking forward to see how you handle it. I could use some ideas!
I have a bunch of pictures I took last Fall at the Speedway museum when the restored car was there for the Unser exhibit. You can see them all here:
Dry fitting parts for front suspension. Includes bits and pies from the 755 kit, the MPC '68 Eagle and shocks from a Monogram stock car, (which will become coil-overs). Torsion bar is still to be added.
