I've heard these and the Chaparral molds still exist. I Maybe the Xerex Special and all the other Can Am car molds are still around somewhere. I could sure do with a series of reissues.
I'll get another of the Trans Am to do a Rockford conversion. I really hope they will decide to do an Esprit or Formula version someday. They had those parts in the kit back around 1974 or so. Maybe the molds are still around. Speaking of that, how about backdating it to the 1976 version just for variety?
Nice project. Can you use the wheels and tires off the Tamiya early VW or maybe the Hasegawa VW vans? I have several of the 1970s issue Revell 911s. They come with those wide two piece tires and I found out that some of the Pegasus lowrider tires fit the Revell wheels and are much closer to the correct stock Porsche tires.
It's hard to say without seeing it in person, but the mid-70s MPC Pro-Stock kits had some slicks that seemed about right when I used them years ago. You might also troll eBay. Sometimes I come across people on there selling bundles of drag parts and you might try that.
I've had luck with sanding the existing paint to get rid of orange peel and rough it up a bit and then wiping it down with degreaser. After that, I shot the new paint and it worked with no problems.
I would love to see a 1/24th Cheetah and also a 1/24th LM002. There used to be a diecast toy one that was accurate and the right scale that I converted into a nice LM002 but I lost it somewhere along the line and haven't found another one.
Hobby Lobby, Michael's and Walmart all sell Washi tape in 1/2" width. It is sold for decorating in the scrapbooking area and is printed with designs, but I think it's the same thing and is pretty cheap to try.
