The modular conversions section of modular fords is pretty good, yes it moves slow, but it's going to no matter what site it's on, it's about 50% real modular swappers and 50% tire kickers feeling out how worth it it will be to do a mod swap.
There is also modularfox.com.
Curiosity runs high for these projects but actual swappers do not.
IMO, don't bother trying to duplicate the modular conversions section from their site, because that section of the site will sit idle most of the time.
