There are a few guys in the area who may be able to help you out. I have used Ace Tire and Auto Repair in San Ramon for tires, alignments, etc. (nothing mechanical) Good people, ask for Tom. I know they do general repair work, I just have never had a need to have them wrench on my stuff.
Also, in Castro Valley on Crow Canyon Rd., Hinkley Auto Tech, 510-881-1052. Kevin is the owner. Reputable place, always busy. Did some work on the wife's car. They do work on older stuff, but expect to pay $$.
I know a few people at Dublin Toyota that know Cruisers, but for your 350, it would probably not be very efficient.
Pete's Gear Shop in Hayward is good for manual tranny/x-fer work. Pete knows Cruisers too.
I'm in San Ramon too, so give me a shout if you need help.
