thats pretty cool actually... replace the pump shaft with something a tad longer, dont bolt it to the flywheel, rather drill its holes out large enough to slip over the bolts themselves, so they act as drive pins (if its dead rigid it can cause issues, like a broken crankshaft, i found), then add an extra outer bearing to the housing using three of its four bolt holes, get the old 5/8 (or was it 1/2"?) star washers as a roller, nut on the end to clamp the whole lot up tight, and you got an easily serviced, virtually bulletproof FD setup.
i havent done an FD setup in like, a decade? but i did find (external) star washers made the BEST rollers around. easily replaced, hardened steel, cheap, etc etc , yarda yarda, rhubarb rhubarb... attaching the engine was the hard part.
