Good luck! Those middle seats can be hard to find since they often got removed for more space and then they were lost or misplaced. If you can find one now days, be prepared to pay a premium! I've seen early middle seats collect a premium. I'd join some vw specific buy sell trade pages on Facebook and keep your eyes peeled. Thesamba.com classifieds will have some listed but those will be full priced and probably far away.

Also, they made a full width and a 2/3rds width seat. Make sure you are getting what you want!

I have one that is in poor condition but I may have to use it. I just thought if I could find one in better shape I might grab it and sell mine. Thanks for yall's help
