7.5-8.8 mustang rear end November 11, 2009, 10:01:00 PM Nothing big or important just a question,... I swapped the rear end out of my 89 mustang GT posi and droped it into my 87 cougar still drum brakes, bolted right up, quad shocks no problems.so the question is ! i could smoke both tires in the 5speed mustang at a stand still and in the aod cougar only the passenger tire lights up:punchballs:??? just a thought either way im still driving it Quote Selected
