First make sure that you go to the bottom of the website. and you will see the classified adds for all makes. There are free stuff, Parts for sale and Parts wanted. If I remember, as a new member there was something about requesting access. I think that was for looking at members project photos. It's great to get in there. If there is not a section called VCCA members only you might look for access but just to post parts for sale you should be OK.
Good luck
I have a 30 so I hope to see your posts.
