are all 69-70 door shells made equal?

[simplyJ]

specifically any difference between the CJ Pony Parts repro doors and the NPD ones? I remember hearing way back that there is only one manufacturer of the 69-70 reproduction doors but I can't seem to substantiate this.

as far as i know there is only manufacturer. i think NPD had them before CJ but that's because they had an exclusive deal for the first year i think.

i was wondering if i was going to have to get a set for my car, but the rust in the corners was very minimal
