I have been a member on fordfestia the protege forums and another b2200 site that i cant find since everything has gone social media.
I own a 1988 Silver CAb plus B2200 and a 1993 Ford Festiva. I found a lot about the mazda truck by raiding the pickaparts for interior pieces for other mazda vehicles. The 1980s plastic fantastic really die in the sun so you get excited over a $4.95 part in a junkyard thats nicer than yours, and i found a lot out of the mazda trucks. Then I scored a 1988 truck for 900 bucks in 2014 and never looked back. Love the trucks. Every bit as reliable as a yota, under rated because the production numbers were so fewer I suppose. Cant wait to come into some funds tax time next year and either do a more simpler miata swap or go for it and do a larger displacement.
