Has anyone ever done this or know how to do it, let me know, thanks Barry

The best way is with a kit. I have some pics on my web site of my conversion to manual brakes.

The only reason I converted to manual brakes was for room under the hood. The brake booster doesn't weight very much to make a big difference in weight savings.

If you have a big cam that the engine doesn't produce enough vacuum for the booster to work, a simple fix is to install an electric vacuum pump to provide enough vacuum for the booster to work properly.
