Problem with selling parts on forums and places like CL is it is local buyers only. I have seen stuff i would buy but not sending $ to a total stranger and hope they do the right thing and ship me the what i bought. I used to like Offer up until you had to give them your drivers license info and pic so they can post it to verify who you are. I told them FU and closed my account. I stay away from FB like the plague. Haven't tried Mercari yet. All the issues with ebay i think is still the best place other than swap meets.
