@Newbie Danny bummer about selling your Speedster. GLWTS, but since you're close-by in Nipomo you should still plan on joining us in SLO for this year's West Coast Cruise. It's a Run-What-You-Brung event so no Speedster necessary to join the shenanigans. 
Regarding VW buses, you should plan on checking out the upcoming OCTO (Orange County Transporter Organization) event in Long Beach. The event is primarily pre-67 buses (split window) and it should give you some insight on what's going on with VW buses (prices and parts availability). There are usually a couple hundred buses there in all configurations and condition, plus flea-market and various vendors. They hold this event a couple times a year.
Usually a few of us SoCal SOCers are there to check it out. You can also check out YouTube for VW OCTO. Here's a pic for visual reference of the event...
