Check the block code. It should be below the distributor, on the block near the split between the tranny and block. It should say D16a6. If it's a D16a6 or the D15 (Hf & Dx-USA..don't know about canada), all still should be a bolt on affair. It's just that the 88's have have 21 splines on the tranny main shaft, but you don't have to worry cuz you're using the motor from the 88 and not the tranny.
