I 've seen several references to parts available from Ground Up in some recent posts. Just wanted to share my experience with them.
Last summer, I did an extensive conversion of my brother-in-law's 1964 El Camino, including replacing the Turbo Hydramatic 400 with a Saginaw 4-speed. He had bought a conversion kit from them a year or so before, but was delayed in getting around to working on it. To make a long story short, at every step where I had to work with the parts from Ground Up, I encountered defective parts, wrong parts shipped, and a less than considerate attitude from the Ground Up people. They shipped the wrong pedals and didn't want to take them back. The Z-bar was incorrectly heat treated and didn't fit and I was told to file it down until it did. Then I talked to another person who said he recalled they had a heat treat problem with those. They did finally replace everything, but it was a struggle at every step and I paid a lot in return shipping. And perhaps most of all, I was turned off by their uncooperative attitudes.
Bottom line, I'll not do business with them, period. YMMV, but that's been my experience. I hope those of you that are dealing with them have better luck!
Cheers!
Chuck
