71' chevelle or el camino?

I would go with the resin transkit from JFP as mentioned above.  The 78 Elky and the 72 Elky were different in the body, not just in the front clip.  Later Elky's were based on the Malibu specifically.  I can't remember exactly when the Malibu became seperate from the Chevelle line.  The big thing is they are WAY different in body style 70-72, and then the 78.  I have worked on both that friends owned.  I worked on those for a long time.  first my buddy's 70 for about a year and a half, he sold it to another friend and I worked on it for the next 3 years.  The 78 I worked on entirely different body, much broader and beefier looking, worked on that turning it into a light to light street burner for a friend who was crippled(crazy guy lemme tell ya).

Jimmy Flinstone does a '72 El Camino conversion for the AMT kit.

What you need is model filler putty or contour putty.  The brand I prefer is Squadron, Green for armor models, or White for aircraft and probably cars (white is a finer grain for smaller scales).  Testors and Tamiya also have their versions.  I doubt Wal-Mart will have it, but a craft store like Hobby Lobby or just about any Hobby Shop will have it.

Good luck.

thanks! i found it right there on the page, exactly what i was lookin for. i appreciate the help.... you wouldn't know a good kind of filler or putty i could use to fill in gaps and mate the two halfs would you? i tried bondo once on a project mustang i built with my little brother, didn't work out too well. i ended up scraping it off with a razor. is there anything similar to it that i could buy at walmart or somethin?

AMT re-released a '72 Chevelle. Box art is red with black stripes. Try modelroundup.com. If you can't find it PM me, I think I have one somewhere.
