Planning a front drum to disc conversion using factory parts. Are the boosters the same for all drum and disc /drum? Do I need to change the booster for this conversion?

Don,
I'm pretty sure the booster itself is the same for any car with power brakes. I know the master is different between manual drums or discs & power drums or discs & the rod inside the car might be different depending on if you're going from manual to power.
I'm sure others know more specifics.

The boosters carry different part numbers, but I've never been able to tell the difference. I've done may disc conversions on A-body cars without changing the booster and had no problems.
