I have that flip front kit and I bought the Revell 66 El Camino to get a good chassis like you did with the 67 Chevelle. I was thinking of cutting off the front clip of the El Camino and grafting it on to the 66 Chevelle 2 door hardtop at the firewall. I haven't checked to see if it will work yet and I noticed that one kit is 1:24 and one kit is 1:25 so I hope they will match up. I plan to build Smokey Yunick's Chevelle that Curtis Turner drove. I know there is a Lindberg 66 Chevelle 2 door hardtop kit out there but have not been unable to find one locally. In fact, nobody carries any Lindberg kits around where I live.
