I have a 1983 SR5 pickup, came with the 22R. I will be installing a 22RE.

Tach: Should be fine, both 4 cyl, right?
Oil pressure gauge: Should I swipe the oil pressure sending unit from the 22R before I scrap it?
Voltmeter: No problems there.
Fuel level gauge: I will have a tank from a EFI equipped truck, has anybody done a straight swap of an EFI tank into a carbed truck.

Would it be easier if I find a SR5 donor?

 

Where are you getting the ECU and harness?

 

I'm looking at getting a complete truck. I believe it's a 1990, not sure if it's a SR5 or not. I figured it would make it a whole lot easier to find a complete truck. I could also go searching in a junkyard.

 

A donor truck would be nice because you would have all the parts you'd need in one spot.

 

complete truck side by side would be the best, thats what i'm going to do when i get my donor 87 Turbo truck for my 79, side by side, pull one motor, swap it in, and have whatever i need right there
