Reproduction exterior door handles question

[MoparDave]

I do have the "challenger" correct door handles in stock.

[MoparDave]

I still don't understand what handles are being reproduced/available   

1970 - early 1971 concave Challenger #2999882-2999883
1970 - early 1971 convex Barracuda #2999816-2999817
late 1971 - 1974 flat E-body #3760214-3760215

both versions superseded at the end of the mopar chain to P3760214-P3760215 these are currently still available from mopar. the 214 and 215 door handles are basically the Cuda style door handle. Unless you know the difference you wont see it.
