Will a tach gauge cluster from an SR5 84 work in an 86?? It has the same profile so I think it physically fits but my FSM has write ups on 3 different clusters so before plopping down $$ for this one, I wanna be sure it'll fly.

I know I have to change the oil sender to a gauge type vs idiot light. What about tach??

Anyone that can give a quick answer who KNOWS?

 

Only if both have carbs.

 

thanks.
