MOPAR 3461187 MASTER CYLINDER...power or not?

[moparfreak77]

I have no idea on what this 3461187 master cylinder came off of but I thought the power and manual were the same? I am trying to get a rebuild kit for it. Did a search on Rockauto for a 1971 Cuda and there are power or manual kits. Does it matter? Are there any good writeups on rebuilding a master cylinder? thanks

The difference between power and manual for a given year is going to be the bore diameter. Obviously, you need the kit with the correct bore diameter. The problem is, there is no accurate universal source for this information. Even if you find a factory reference for it, it doesn't mean the manufacturer of the rebuild kits got it right. So measure your bore, and buy a kit from somewhere you can return it. Probably smart to order both and return one.
