No one interested in doing a hoarders club with at least a parts register so when there is a need there is a collective pool of parts to ask about? A group could even identify and buy desired pooled parts for when people have a minor bump or any hard to find discontinued parts to buy if and when they become available? Just need to be sure It's a trusted parts storer if doing pooled purchases, wouldn't matter if it was a maintained up to date list of parts that people could look to draw from as needs occurred.
A lot of vintage classic car clubs do forums and sell parts as well, why not have the same for Supras. A cooperative and coordinated effort to pool and share/sell parts?
