can any one tell what I can do about fixing my 96 ford mustang 3.8 l, it has a manual T5. BorgWarner 5 speed and I bought it from a kid that place a 97 3.8 l automatic motor in it with all the old motor parts from the oem motor out of the manual96. I think the balance is off do I have to buy a new 97 flexplate for the 97 auto ,trans motor and then take it to a machine shop with the flywheel from the manual to have the set the right weight and balance like the auto plate had to get it to stop shaking the hole car??? is there a flywheel any were that will match up to the auto 97 3.8 flexplate that will work in the manual 96 with the t5 trans [please help. could my synchronizer cam position sensor be the wrong one too?? can I buy a truck or another flywheel from store from a different mustang year or size?
