They have both in stock-the '68 2-in-one convertible (you need this kit for the small block hood), and the '69 coupe listed as a 429 but it's a 427. It's discontinued, but they have them in stock, also they have a current Baldwin Motion '69 that would give you the proper coupe body. These Revell kits are excellent. I've built the '68 convertible.
These rims don't come w/the kit. The kit has rally wheels like the one you want to build.
