I found a complete factory tach cluster out of a '77 or '78 Blazer in nice condition at my local honey hole. He's asking $125 for the complete cluster. Lmk if anyone is interested, I can go grab it!

Yes it will. You need to trace the printed circuit on your cluster and move a couple wires in the plug to match the new cluster. The tach has it's own separate plug that you can do with spade connectors, Pos. Neg. and tach signal.

The fuel gauge will work, but if the resistor on the back of your gauge is different than the blazer's that needs to be swapped. (factory resistors are different colors for different values)

I know in the past, I've had issues putting a truck cluster in a k5 without some dash frame trimming, so I didn't know if it was the other way around, as well

Sweet. I'll think on that one.

If you haven't already please grab it. I am interested.
Ok, is there anything else you might need to make it work? I could see what all that Blazer has, like tach filter??

The gauges have nice color for being 45 years old! The oil press is a manual gauge

Nice score! I'll take one for an '84 non-tach(or with to be honest) unleaded please. LOL
I should have a stock one w/o tach from a 81 with a working clock in the bottom left position.

I'd have a look. Seems rebuilding mine is tough with availability on some of the re-pop parts.
