You can use the front and rear differenetial off of the 89 RS, along with the wheels. Everything else is a no go. The differentials are geared at 4.77 versus the stock 4.30 you are runnign so that is an improvement fo acceleration, though a decrease in gas mileage if you put those in. Most people like them if you offroad, and I have them in mine for that very reason, makes up for the increased tire size.
if it was an 93 RS, you would have a lot more in common.
