Will a 2003 aluminum master cylinder bolt up to a 72 booster?
 

LS swapped my 72 and will add the hydro boost when time permits...will the master cylinder work with a 72 booster...for now?

Try and stuff it on to find out. Though I doubt it, since the newer stuff is metric. Is the hydra-boost off a truck with a similar weight distribution and brake size, i.e., swept area, front disc/rear drum, etc.?

The master is off a 2003 2500HD...rear disc. my 72 has front discs and rear drums. I figured the flare fittings would need to be changed.

Interested in this as well. I was actually thinking of using the booster/master cylinder combo off the donor vehicle.
