In the past I have installed a Ron Francis kit in a friend's street rod. I was impressed with that kit. However, his prices are out of sight now.
I just bought a kit from Hotrodwires and I'm very impressed with the whole deal. There is a fusible link at the starter. The tech is available by phone on nights and weekends for any kind of stupid questions. It has quality components and their attention to detail is good. The price is right, but the instructions could use a few more words. I would purchase from them again.
