question about getting rid of some parts

[1970 C10 MJW]

I have several parts that I would like to give away if people will take them... but I also have a few I would like to ask some money for.. how much does it cost to be a member and what do i need to do, before I pay to become a member would anyone be interested in a set of old camper mirrors they are in ok shape not perfect by any means but still looked decent, they are the ones pictured on my truck in the pic of the day I brought it home, I have since put the 69 round mirrors on.. also i have a set of original arm rests I would like to give to someone if they will pay the postage, the drivers side has a couple tears but the pass side still looks decent, I have a set of 52 pads that came with my mcgaughy (however its spelled lol) disc brake kit, that I would give to someone in need of them if postage is paid, they were never even installed, I have wagner thermo quits on my truck, I will have a few more things that I may want to sell trade or give away. let me know what you guys think, Im not trying to break any rules, im just seeing if its worth my time...
