I bought a kit. It's not that I'm lazy, I just figured my time is worth something, and when figuring my time plus the parts scrounging plus the "engineering" to make it work, I couldn't justify doing it myself. I love scrounging and DIY, but not in that case.
One solution for you would be to convert to '63-up mechanical clutch linkage, but you'll need a later bellhousing too.
