Mechanical Fuel Injection for Nailhead Buick

I had a Nailhead Buick for which I had a mechanical Hilborn FI set up put together. I changed my mind and changed those parts necessary to use Holley electronic FI with the Hilborn manifold. I have the mechanical parts swapped out for electronics. I ***ume that these will fit a Hilborn FI set up for a SBC or other engine. The mechanical parts were only used for about 4 hours of running.
