I replaced the glow plugs and the fuel primer pump.
I dug up a Mercedes 4-speed manual transmission at a junk yard. I took the bell-housing off of it and fit it up to the engine.
I think I can use the bell-housing from the Mercedes transmission on the Chevy transmission and get it all to work. I'll have to make some sort of custom plate to connect the two, but the Mercedes bell is an inch shorter than the Chevy bell housing, so I think I have an inch to work with for an adapter and spacers.
