I have both the trans am and 69 firebird kits and was not at all impressed with either one. As a matter of fact I glued the hood closed on the firbird. Seeing as how these are my favorite cars I was highly disapointed with the detail, especially in the engine compartment.
I concentrated on the outsid since they sit in a display cabinet. You seem to be doing one hell of a job on this build, I will be watching closely to see how you improve this kit.
