Selling “period correct” parts question

[Steve67RS/SS]

Hi Guys, well I’m getting close to the end of my build on my car. And I figured I would try to sell a couple things that maybe would be more geared to some that build to more of a period correct car? I have, I think, a late 69 12 bolt posi. And a few other things. So my question is, do you know of any sites geared more to that? I wasn’t sure items like that would interest anyone here, And coming up with would be a fair price on these and other things is proving to be just a shot in the dark..thanks for any help, I wasn’t quite sure where to post this.

Thanks, Steve
