92 Mustangs did not have a C-4 unless it was swapped in to the Mustang . It's an A4ld etc based on the C-3. Check to make sure. If it's a C-4 the bell will not fit unless you find a C-4 bell housing, flex plate, converter for the 2.0 etc. Pretty pricey. What year is the Pinto ? Good news however is that are allot of 4 speeds around to get parts to rebuild the 4 speed.It will be allot cheaper .The 4speed in the Pinto 2.0 and the 2.3 should be the same and rebuilds are not to expensive or finding a good one. One more thing is that the Merkur XR4ti 5 Speed (should) bolt onto the 2.0 bellhousing as it's the same as the 4 speed but it has an overdrive added.

what exactly do you have?  if the pinto is a 78 it def doesn't have a 2.0 L in it unless that too was swapped in as the 2.0 was dropped after 74.  that said if it is a stock 2.3 find a t5 out of a 4 banger fox mustang pref 89 and newer as they are all w/c past that point. The merkur trans mentioned above is known as the T9 and is basically the pinto hummer with a 5th gear tacked on. It will bolt in with the added bonus of not having to trim the shifter hole to get it all to fit.
