I had the Ford system all laid out but never tried to install one. The trick piece was getting the distributor converted.
I shared the info quite some time ago with one of the guys here. He went through the install but I haven't heard from him in a little while.

With the effort and expense of gathering parts and doing the install, you might as well get a complete aftermarket system.
You're not really going to save any cash by piecing something together.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
