I totally concur. The first "brand-new" car I ever purchased was a 1977 El Camino SS, EXACTLY like your replica, except the interior in my 1:1 scale Elky was black, and I kept the stock rallye wheels. Seeing your buildup brought back a flood of fond memories for both me, and my wife! I totally LOVE this build!!
IMHO, you should get with a resin-caster, and create a master for this model!!
My sentiments exactly! I have one of these in the unbuilt pile, and was really looking forward to the build, as this is, hands-down, one of my favorite GTOs of all time. After seeing a superb build on this poorly-engineered kit, I'm considering a trip back to my single-digit childhood, where I'd throw it together in an hour, and roll it down a high-slide, into a burning pile of leaves, with the interior packed with firecrackers.
