3 hole gauge cluster modified?

[bb400ho]

I'm looking for ideas. I have a 68 GMC with a 3 hole gauge cluster. I put a 5.3 ls in the truck. can you add a clock or tach behind the center hole and keep the turn signals? curious to see any mods.
thanks Bryan

I think the hardest part is finding gauges to fit. Use the search, others have done it with after market Sun gauges etc... I did the other option, custom glove box door with 93 Caprice bezel mounted with some after market gauges.

wow thats cool. i didnt realize that the glove box door would fit like that.
i am looking to see if there can be something in the center hole and keep the signal indicators. i dont need the idiot lights.

You would have to relocate turn indicators to the same position as the full gauge clusters have. I see people using the small green led lights there.

Years ago I did the mods to put a factory tach in that spot. The tin has to be modified ( hole with rolled edge) It came out very nice but still a lot of work to make it look right.

I have thought about a clock from a 65 Chevelle in that spot as well.
