Well, doggone, it worked! I guess I should explain that last picture....
It's for my Matador; I'm stuck right now and I hope this group build will help me get if finished.
I took the AMT Matador kit, cut the front clip and rear wheelwell on back from the chassis, and grafted on a front clip and rear wheelwell/trunk floor from an AMT '95 T-bird kit.
I made a new driveshaft tunnel with the remains of an old Coke can.
Then I took the '91 Monogram Pontiac Grand Prix roll cage; cut off the crush panels, and glued it in to place (it fit really well both on the chassis and under the roofline of the body). I also salvaged the dashpanel of the Grand Prix kit (all of the black pieces you see), connected it with a scratchbuilt dashboard, and then made new crushpanels.
Not pictured is the racing seat, which is from the AMT t'bird kit. I cut off the headrest and will add one onto the back hoop, like you see on the old Monogram kits.
Whew, and you wondered why I was stuck; I don't know what to do next
