Update:
I took the starter to a local shop. He could not match the bendix up as it has an odd number of teeth and rotates opposite of most (?) So he suggested welding the hub of the bendix to the outer cage. We both agreed that it should be fine for the use it will see.
I found a tank that will work, off of an old Wisconsin I think. I will use the existing sediment bowl and screen and add an in line strainer just because. Based on the mounting position I came up with the return line from the injector will be only 2 inches below where the line will re-enter the tank. I didn't want to permenently alter either the engine or tank (which is 50 years old in itself!) so I drilled a hole way up on the filler neck just below the cap and soldered in a 1/8 in steel pop rivet. It will always be above the fuel level and can easily revert  to a usable gas tank should a Lister tank ever be available.
And the crank handle just needs to bent and welded to the fab'd hub i made. Now that the starter is serviceable the crank is a secondary project, but I get it about the safety concerns. I have played with flywheel engines for a while now and cranks scare the hell out of me. Would much rather spin the wheels manually.
Hopefully by the end of the week I should be ready to unleash the beast! I know, I know...pictures!

Well, I have another question. Maybe this will get a response. On the top of my LT1A there is a spill pipe (?) exiting from the valve cover which is supposed to lead back to the tank. I assume it is a sort of return line? My question is this: how much pressure is that return fuel under? I am trying to adapt a tank to fit and I do not know if that line can run upwards about 1 inch before entering the tank, or if it must be level or slightly downhill to the tank?
Also am looking for a bendix drive (11 tooth) for the older style starter, and a crank (ccw old style). Thanks!
