The 91-93 Tbird 5.0 is VERY close to the 94-95 Mustang 5.0, with the exception of the water pump/fan, and exhaust manifolds. The exhaust systems are completely different, the Bird uses 5x4.25 bolt pattern compared to 5x4.50 bolt pattern, and the Bird has IRS. You can get detailed information and help at

These are very nice cars, but do take a little extra to get around these difference, and not many suppliers for the MN12 series parts.
About the only Mustang I would trade my Bird for, would be a new GT500.
