How many different instrument panels?

[heavychevy79]

How may different versions of (Scottsdale, Bonanza, Cheyenne Super, Silverado, Sierra Grande...) IPs did GM use from 73-87?
I know dummy lights won't interchange to gauges without modifiying the wiring, so I'm not including those in the question.

I know of 3 different ones in 73-80 alone, 73-74 has a hard oil line going to it.
(pic 1 and 2) PN 8917775 PED-2 It's from a Cheyenne Super.
(with this IP only the volt gauge works in the 79)

Next is out of a 78 Silverado I'm building (pic 3) PN 25017325 PED-3

And neither of those will work in my buddy's new 79 shortbed Bonanza
(it has an IP with same PN as my 78, and only the temp works)
so there must be a third curcuit board for 79 and 80 that I need to get.

Also I would like to know what gauges will interchange with what panals.

I know there are at least two different IP for 81 up trucks, one similar to the
73-80, and one with a fiber optic sensor. (pic 4 and 5) PN 25088586
RV Truck 42/772 From an 88 Suburban.

I hope that was all clear and understandable.

It would be really great to fill in the gaps here.
