It's not as easy as it first sounds. Just like L48, I have done it in the past with a chevelle, but there are differences and you need the vacuum source. I also have a manual system that I was thinking of converting to power. First, get all that old brake fluid out of your system. Get some new quality brake fluid and drain all that other 30 year old crap out of there. Do a real good bleed job, and you might find - like I did that the manual's aren't too bad. At least I can live with them for a while now. I'm also looking at a hydro boost instead of power assist. There are some old posts on it that are interesting.
