Correct.the master bolts right up.IIRC you can get a drum drum master and when you add discs there is a tiny piece in the port for the line that can be pulled out so no pressure stays on the discs.We have 70 c masters on my 65 manual and my kids 62 300 power drum.If you have power you will have to check and maybe adjust the rod for the master.My kids 62 was a single so we needed to thread the rod out a bit.I got both at Advanced remans.No problems after at least 15 years.Rocky
