Disc brake conversion kit recommendations...

Aerospace components makes a very nice kit if thats what your looking for. It's very lightweight compared to stock drums. Probably will shave over 100lbs unsprung weight from your car which is huge. Will also get you the bb pattern.

It all depends on how much you want to spend and what your skills are.

There are many ways to upgrade your mopars brakes using stock components as well. There is a ton of interchangeability with mopar brakes.

There is an article in the current Mopar Muscle issue where they upgrade their 68 Barracuda drag car with Aerospace brakes front and rear. They were going from 73+ A-body disks to the Aerospace disks on the fron and drums to the Aerospace disks on the back. They saved 86 pounds.
