I bought mine from rockauto.com, $30 I think. Had to bend the hardline like zKars says. One thing that made for less bending was to swap the hardlines from right to left and vice versa. Not stock but darn close. Or you could buy the right angle inlet from MSA for $200 each. Thinking back there was something about the adjuster arm I had to redo after I had them both on. Seems like it had to be bent to catch the adjusting wheel notches, when I pulled the E-brake nothing happened and it should have.

I'm 99.9% sure the '78s had the switch in the oil pressure sending unit. He may have the wrong year oil sender or the wire could be loose or corroded.

Boy oh boy is that true! I got a ZX motor a year or so ago and they came with some chain and a big arse front end loader. I got them to let me go home and get my tools, came back and for $50 less they let me disconnect everything. They did put it on it's side for me first to get the low stuff then righted it up for the rest.

Average price is $7,500 according to Hagerty's. I'd think it's a #2 or #3 by your description. https://www.hagerty.com/valuationtools/HVT/VehicleSearch/Report?vbe=63940

I've thought that maybe your throttle plate is crudded up around the bottom and not letting any air pass by like it should, it affects idle. It may not help your current problem but cleaning all the electrical connections is always helpful. You already know about atlanticz's tech tips so look at this, http://atlanticz.ca/zclub/techtips/electricalconnections/index.html

...and things you should!

The vacuum hose going to the fast idle actuator may be cracked or loose. When they are working properly it will pull back the throttle rod raising the idle to compensate the drag from the A/C compressor. Quick picture I grabbed off google, maybe you can see what I mean. FICD is "fast idle control device"

Is the new fuel filter's arrow pointing toward the engine? If it was starting right up before you did the things you mentioned it has to be something simple. Are the thermo time plug and the coolant sensor plugs reversed at the thermostat housing or possibly the bullet connections? Just guessing this morning, you seem to know what you are doing so I apologize for sounding pretentious.
