Nothing wrong with a quick build. Believe me, you're not the first to get the pistol grip backwards, and I bet you won't be the last. If you're not a Mopar guy, it's easy to get wrong. Good looking build.
Steve, first let me compliment you on your build, it looks really good. Would you mind telling me what parts and pieces you used from each of the kits you mentioned? I had a 1990 Formula that I'd like to reproduce. Looking at the three kits you mentioned (on ebay), I see the '85 TA would supply the rear spoiler and the '92 the wheels and the body. I can't see what the '91 would supply though. Finally, where did you get the front bumper? Modify the '85 perhaps? Thanks for any info you can provide.
