UPDATE! Reply from Altered States. Got a reply from AS this morn and he states he does make an G-B-P body ...This is a relatively short wheelbased car so the Garlits Wynns Charger should be a good donor.
That's good news!
Re: the chassis, the Garlits chassis has a fairly unique roll bar shape (a shallower angle), different than the 3-point on the G-B-P's Rod Stuckey/Kent Fuller design. Maybe AS's own 186 chassis, shortened, would be a good donor. Certainly worth asking since the gallery shows a completed car and he would probably know. Other sources to consider for a more appropriate shape might include the Revell Tony Nancy Double Dragster kit (IIRC the 22 Jr. Comp. Roadster is a Kent Fuller chassis) or possibly the Ramchargers or Tommy Ivo kits. Regardless, all of them would require extensive shortening/lengthening and reworking.
