All,

 

From what understand, there should be no drilling at all involved!

You just need the right mounting plates.

Thanks,

 Not so. there are two studs # 384463-5 I think, that hold the bottom of the pedal bracket on a non-power brake set-up. These are screwed into the pedal bracket. It is these holes that have to be drilled out so the lower two attachment bolts on the booster can pass through and have the nuts hold it all together.

This of course is referring to a power brake booster upgrade for disc brakes on a non power drum brake car. I'm sorry if I got off track on this as I think jowens1126 really wanted to know if the spindles are different on factory drum and disc cars. In that case I do believe they are. Some conversion kits such as the SSBC one I installed, fit factory drum brake spindles, so no change was necessary.

For whatever is worth it, here is a picture of the template that comes with the LEED brake booster. It shows the difference between the hole location of manual vs. power brakes. The hole of the power brakes is about 7/16" higher.
