How about a 97 GTP?

Why, stock equivalent to stock iridiums. Same .040 gap. Used them before, worked great, though short life;40,000 max miles and they were beat. Why you say dont use? I only use NGK and Autolites, whatever of the two on sale. I have copper now and not happy with them. Tried 3 sets of different brand stock and one hotter heat ranges of copper plugs, all the same gives an at idle miss, best performance for 2,000 miles then drops dramatically.

I would wonder about the shape of the end between the 2 companies.

Otherwise I doubt it matters.

I actually like Champion's because they are still made in USA. but I digres

I have these AutoLites in our Enclave and while we don't have a ton of miles on them, we saw NO issue since changing them to these. The stock ones had 95,000 miles on them and still looked DANG good.
