George, what car are you wanting to do? There are plenty of resin bodies out there. You should check out Compresins.com to see the bodies they have on offer. Also, check with Slixx for the decals that match the funny car bodies. Hope this helps.
As I've given up on Revell and it's love affair with "vintage iron" these days, I'm hoping that Tamiya would take a serious look at the Aussie Super V8 series. There are only a few brands on the track but a company like Studio 27 (a Japanese Slixx, if you will) could fill in the gaps with all the available teams that are currently competing these days. I'd buy more than my share from both Tamiya and Studio 27 if they would get around to kitting these cars.
I have to say that along with everyone else I am beyond impressed with your fabrication skills in model building. What gets me about this build is that it seems like we're following along with a build up of a full size car as you're leaving no stone unturned when it comes to detailing. What also impresses me is that your photography makes it seem like you're building a full size race car. Based on what you've done so far, I have no doubt that this is going end up being what I call "GSL Best in Show" worthy. I'll go so far as to say that it could very well end up being an IPMS Nationals "Best in Show" worthy. Keep up the outstanding work. Looking forward to the next update.
I don't know if anyone has mentioned it already but I'd love to see Revell (or anyone for that matter) come out with a new line of current 16 th scale drag cars and ( very wishful thinking with the liscensing issues) Nascar cars annd trucks. My thinking is that all they would have to do is come out with a few cars and then Slixx or someone else would take over in producing many more decals for other cars. I believe that the aftermarket would supply additional funny car bodies and if Nascar cars were being produced, the aftermarket would be ready and waiting for them as well. With many of the fringe modelers getting older, this scale would seem to be a no brainer
