Thanks for the kind input, the very astute and valued observations afforded. Very interesting both photographs, whereas I like the screen vent of the trunk area via the taillight cluster assembly - something I might not have noticed for a few weeks just examining said image. Thanks very much for sourcing the photograph, indicating the venue, and pathfinding means to understand and interpret just what is being seen.
The wrap of the steering wheel rim seems only to show up for the instrumented test session hosted by GM, whereas I think I might cut my wheel to fit something that might be finished to suggest wood. I rue 'painting wood', and may look at other models or hobby supply sources to perhaps find a wooden rim to employ here. I should be able to make better progress soon, having spent perhaps a bit too much time on the air cleaner assembly.
Though a project not soon to be tackled, this weekend I picked up a 1:18 Yat Ming/Road Legend '69 Pontiac Trans Am (a dreary tool this) as well as a 1:18 Lane '68 Firebird (an exceptionally fine tool this) with the hope of eventually mating the stack of parts into a backdated '69/'68 Firebird Titus racer. '69 shell, '68 hood scoops, faux '68 side trim, rear bubble flares (mild these), and the distinctive '68 'beak' fit to the panelwork of the new car. Given the front bumper was painted (fiberglass replica or aluminum perhaps?), hacking and slashing to mate the same to the Yat Ming/Road Legends shell should be doable. As an aside, I wonder how they homologated what seemed a Chevrolet Camaro rear spoiler? It would be fun to have two - one the anticipated and ready to go '69 Tunnel Port 303-powered racer, the second what they were effectively forced to compete with as outlined above with Canadian Chevrolet/Acadian power. Not to be seen soon, but parts being gathered for an elaborate future initiative. Thanks so much...
