i do not know about the '94+ cars..
the MN12 uses the same starter in all the cars.. be it an auto or an manual, but i'm not 100% shure about the 4.6L and the 4R70W equiped cars?
Also the S/C and F150 flywheel are the same diameter witht he same tooth count (going by looks.. i never felt like counting them all
) .. the only this different, is where the ring gear is located.. the SC it's on the leading edge, on the F150 is on the Back edge of the FLywheel..
Hence the difference in the starters
you can rebalanced the s/c flywheel and use the orginal starter from a MN12..
Or you can buy a F150 flywheel and a F150 MANUAL starter
OR get a F150 flywheel and move the ring gear and use the stock starter
Also the S/C (least '89-93) uses the same clutch as the '88+?? (M5R2 equiped) F150..
and on a 5.0L requiped car.. the m5r2 swap is a 2-3 day job working like 6-8 lazy hours a day by yourself
