Got the engine fired up, it had a horrid injector knock on the front cylinder. Tried swapping injectors but the knock stayed in number one. When I'd break the line it had almost no effect on the power and it seamed to be pumping way too much fuel. There's a check valve at the top of the piston in the high  pressure pump, thought it might be stuck so I gave it the atf acetone treatment overnight with a tube feeding it. The next day the knock was gone and breaking the line now makes the engine die.
Was given what turned out to be the rear driveshaft from an 80's Bronco. Looked like a likely candidate, so it was shortened and adaptors made to mount to the gear box and flywheel. Also made up a shield for the flywheel.
