I've wanted to build this but 65-66 Vette's are a bit of a challenge to find let a lone pricey. I recently got a junk 66 body that I was going to build a custom Vett but since going through a lot of pictures looking for SCCA cars gave me the idea to cut the louvers out of that junk body and replacing a parts box 63 Vett. I found a custom hood in my parts box and it so happen to be a 66 BB hood ( I'm filling the hood louvers to make the correct hood ).
Here is the start of that cutting up, I have the correct interior from the 66 Vett so I have the correct seat pattern. What I'll do is shave off the emblems and use some decals I have to look like the 66 script. The rockers are grooved on the 63 and flat on the 66 so I'll just sand them down.
