On my 91 I keep going back and forth on what gauges to use. I can only think of a few reasons to keep it electronic but I dont know the whole scope of the system.
1 its quiet and accurate.
2 I already have it
3 I dont have to repin the connector
Now my non coherent thoughts on cons:
My plan for the truck is to have the most reliable and common parts so I can eventually be on a road trip and walk in to a parts store and be on the road again. Speedometer failure is unlikely and not critical but why not consider it.
Drivetrain is p pump 12 valve cummins which is all mechanically controlled. Hydro clutch nv4500 with a gm 205. Pretty rock solid idea there.
I currently have several tach clusters and my stock non tach 91 still in it.

I'd like to use these two gauges. They are new gm mechanical 5 digit speedometer and the 4k diesel tach.
5 digit kinda sucks. On the lookout for a new 6 digit. I dont think mechanical 6 digit with trip exists.

Problems here is I dont know how to put that tach in my current cluster.
What do I do with the left corner battery light? I want to have a boost gauge there. I know I'll never have 150 psi boost but it's a cool factory gauge.
It has two needles independent of each other.

I will be losing the tbi and the 4l80 so what does that leave for electrical components? Will the speedometer function after that?
Knowing much more than I, how would some of yall go about building a cluster for a truck like this?
There are many more questions I haven't even got to yet.
Thanks for getting to the end of the rambling.
