Greetings and thanks for inquiring as to the status of what I do in-scale...
A bit hobbled as of late - perhaps dedicating too much time to a Mark Donohue/Penske Racing side project of long interest even as it's not strictly SCCA Trans-Am rooted? Although likely to return to chassis work across both the '70 Chaparral Camaro (it still needing decals/graphics) and '70 T/G Racing Firebird Trans Am projects, seen (very) briefly would be a 3D-print shell of a '72 Matador NASCAR racer utilizing Jo-Han '72 Torino, AMT '74 Matador and much later AMT '92 Thunderbird NASCAR parts and subassemblies to approximate what's needed.
Perhaps I viewed altogether too many (late period) episodes of ADAM-12 when it was in syndication as a kid, or longed for the COX .049-powered Matador perpetually out of reach at the local K-Mart so long ago, but something within myself needed and still needs a 'Flying Brick' to display next to my Trans-Am Javelins builds/efforts to date. Thanks again and hoping to return to productive form as the weather turns and indoor activities beckon...
The topic in '72-season form, mainly because I expect someone or some firm to eventually afford us a fully finished '73 Riverside winner if only because to-date they've afforded us everything M. Donohue ever drove, rented, or glanced upon...
Seen here is a much-modified $29.95 eBay-sourced shell (actually two), with a dead example (yes - a third shell hinted at here) having been cut apart to yield separate bumpers, the grille, plus hood and deck lid as-witnessed. The body shell measures out at approximately 1:26th scale, hence some complications are introduced on that basis besides. Very slow work, and not for the timid.
Other pathways would include the scarce Model Car World resin transkit of old, as well as better quality 3D-printed shell plus separate bumpers and grille sold by Robert Burns/Too Many Projects. Decals will mostly be made up of Cherry Run '74 Penske Matador graphics, Dave Van Decals (perhaps), and whatever stray items might otherwise be wrangled and deployed just-so.
And finally, shared is a quick view underhood evens sans roll cage/stiffening structure characteristic of most any NASCAR/Winston Cup topic. The engine constitutes a mash of Jo-Han and AMT parts, and more that a bit preliminary it is with regards to appearance.
