88/91 RT engine swap

My 88 RT engine has a coolant leak (cracked head or bad gasket or sumpin') and I want to swap the engine out of my 91 into it cuz it ran stronger anyway, plus it has a block heater which is nice when it gets 20 and 30 below around here. Both d16's with 6 speed manual. I want to keep the 88 trans tho - the 91 doesn't go into reverse very smoothly. I know the clutch, which I want to replace, is specific to the 88 and I am assuming the 88 trans will bolt to the 91 block but I will have to keep the flywheel from the 88 with the trans too. Am I right here? Any other issues to know about? I searched and got a lot of responses but couldn't find these answers. TIA, much appreciated.

    Sounds like you have it figured out. Use the '88 engine harness as well.

    Didn't even think about the engine harness, but that reminds me I was also wondering if I should swap out the ECU?

    Thanks guys!
