At my wit's end
I checked ground and it seems to be fine. It is just going to the body right now. When I swap out the HEI module and put a new heat sink on it (current one is just a make shift piece of scrap sheet metal anyhow) I'll put a proper ground on over to the alternator ground.
PM'ed Dan to see if he still has any NOS 1920's lying around. If not I'll just get one of the floats from Walker, which is way cheaper than any of the parts stores list it for direct from their site.
