Hi Brian & others
Many thanks for your replies. The idea of fitting a '68 master cylinder is a good one, though from what I've been reading its important to use a drum/drum master cylinder, as most of the aftermarket kits assume disc/drum and the disc part of it won't send the correct quantity of fluid to the front drums, and won't have the correct inline pressure valve.
My question is, did the '68 C10 have drum/drum or was it disc/drum? Sounds like a straight swap only if its drum/drum?
Checked out those links thanks, but still struggling to find a drum/drum dual circuit master.....
Thanks again
