Yeah, my bad
The gear's are supposed to be out of a 89' SC, I blew the differential doing very stupid things w/ my car and i had to replace them...took a good day to figure it all out.
as for the motor, it's either a 93 or a 94, not completely sure. The guy i bought my car from said he blew the old motor, cause the head gasket's went and he kept drivin it...and when he had the new motor put in, he said he requested a Mustang 3.8 and that it was either a 93' or a 94'. i've pretty much just assumed it was a 93'. if i find out it's out of a 94', then i'll be upgrading to RollerRocker arms as soon as i have the cash. because the only set of Roller Rocker's i've found are for a 94-97 3.8 N/A.
