I did my '90 a few months back. '87 thru '90 only,otherwise as stated above you'll be swapping cables also.I got the wrong one first time around and speedo hook-up at cluster was different also the indicator lights on the left panel.Once I figured out right years everything was exact match.I got a tach for my auto trans which is helpful.Sensors I also got at wrecking yard,not a problem so far.Oil sender is the big brass canister looking one,versus the small one you now have.Temp sender on head back by the firewall looked the same as old one but it isnt,donor vehicle should have the right one or look for one that had gauges in it.A sure sign it had gauges is the big oil sender still there.Dont worry about mileage if you have patients youll figure out how to roll that to match your vehicle.Use your old one to practice on.Hint:number dial can be pryed out carefully,partially seperated to roll numbers to match.
