Check out the Antique & Collectables Kit. I just built one and found it to be an easy kit to aasemble. I didn't need a donor car and there was no welding to be done. As for the body, you can get it in a gelcoat color of your choice that already comes with a high gloss finish that requires no sanding of mold marks or seams. There will be some cutting needed such as for the sidepipe cutouts and holes for the bumpers bracket bars, roll bar, hood & trunk latches, and windshield posts.

Hope you like what they offer, I did! Have an enjoyable build whatever kit you choose.
