There used to be a chain outfit Service Center - Speed Shops
in Concord Ca., I use to go in weekly at a min.
the guy behind the counter was the owner,
he was always willing to help, had a decent inventory
usually had to order anything I wanted
I worked at Monument Automotive Supply, as a teen
Concord, Pleasant Hill & Antioch,
they had a decent lil' display wall & racks, a huge catalog area to browse
them big 5 hole steel stands on the counter, with every speed supplier
whenever I was working, not stocking shelves or delivering something
I was behind that "Speed" counter
I sold a crapload of performance stuff from there
most all my checks went to performance parts too
Bailey's Brothers Speed shop (speed & marine)
Vallejo Ca. were a top-notch speed shop & maching shop
their main business was Dirt trackers, Sprint Cars & Drag Racers
Morgan's Machine, Marine & Speed Shop, in Walnut Creek Ca.
Tim Morgan, he actually campaigned a T/F dragster
& a T/F Hydro IHBA drag boat, that had a couple of records
it was a cool store that had the dragster & fuel Hydro on display
good machine shop
We had a Super Shops in Vallejo Ca. IIRC too
Tognoti's Auto World was a cool place too, Sacramento Ca.
it was full of cool stuff & usually some race cars on display
Vic Hubbard's in Hayward was a great place too
right off the hwy-17 back then (880 frwy now) a sponsor of mine too
Gotelli Speed Shop in San Bruno Ca.
Flowmasters was in Santa Rosa Ca.
I'm sure I'm missing some of them too
