Never heard of Scale Auto Decals, or a conversion kit for the AMT Gremlin who makes what. Great build
The decals were from Scale Auto Details (my company) and some of my decals have been reviewed by Gregg in Model Cars Magazine. I have a Fotki album where I show many of my decals and some of the resin parts I sell. You can access the Scale Auto Details album at this link: http://public.fotki....caleautodetails
Resin parts are available to convert the AMT (R2) '76 Gremlin into a 72-73 Gremlin. Another path is to use the 72 front end (grill/bumper and front pan) from the old AMT Gremlin Funny Car kit and cut the rear '76 bumper apart to simulate the 73 bumper/pan.
