brake booster question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm sure I should already know this but I don't. I found a '69 I'm trying to work a deal on and it has power drum brakes. I'm assuming the m/c is different if I go to discs but is the booster the same? If not and I get a new one will the mounting holes line up? Thanks.

Booster oughta work ok. Be sure its shaft mates correctly with mc where the mc MAY or MAY NOT have a bore in its piston, in which case the booster shaft must extend beyond its mating surface to where it nearly bottoms out at the end of the bore; & vice versa.
