my 65 has that same master cylinder, the right reservoir is for the clutch. I was able to get a replacement with the right size bore from o'rielleys auto parts store... was around $200, if you want to get away from the o.g. m/s captain fab on this site sells a kit that splits the clutch and brake m/c. his is for a c/10, but should fit your firewall...


the tach , while in the right spot is an aftermarket piece.

"Interesting that it's 5 lug front and 10 lug rear, is that common? I don't know anything about the bigger trucks.
It looks to me like manual brakes too, which I wouldn't expect."

the 5/10 is common, if you notice the front wheels are still drilled with the 10 bolt pattern... there is a big vacuum booster for the brakes located under the cab.
the rear also has dual wheel cylinders, one on the top, and one on the bottom of the backing plate..

cool truck!
