Just wanted to throw this out there so no one goes through what I did this weekend. We changed the motor mounts on my friends 89 hatch.
1) Evidentally there is a rumor that you can change your hatch or notch model motor mounts for the tougher convertible motor mounts. We tried and failed. While in theory I could see it happening if one were to cut the hole in the frame a little while dropping a hoisted motor in, I cannot see this ever working while just jacking the motor from underneath. They just do not line up like the stock set, and the pitch is way off.
2) We exchanged the Convertible MM for the stock set at Advance. The stock set required fabrication:
a) We had to change over the brackets that mount to the block for use on the new mounts. They did not fit the new MM.
b) We enlarged the screw holes using a step bit... That worked. Unfortunately it was crooked when we finally got it on.
c) We filed the bracket so that it would fit correctly... Then it was at least half an inch off from the block holes when we finally went to put it on
d) So we drilled a hole next to the original holes on the block bracket and connected the holes (We slotted the bracket) so that we could slide it into correct placement. That worked.
What started to be an hour job turned into half a day, so just thought I'd throw that out there
