I did this with both my 66 Mustang and 65 Falcon using 99 V6 T5's. You will need to swap the tail housings if you want to use the mechanical speedo. There is some grinding required on the housing to accept the oiling tab for the 5th gear cluster on later trans. I did it with a die grinder and some small aluminum carbide bits. The 96 and up T5 has the same longer input shaft that came about in 94, so you'll need a 94/5 V8 bellhousing to use the 157 tooth flywheel or use the V6 bell but it'll require a 164 tooth flywheel for the starter to properly engage (found this out the hard way on my Falcon).

Something to consider.  If your car has factory power steering, the 94 and newer bellhousing and tranny are not a good choice as they relocated the release arm to a lower position and it will interfere with the power steering ram.

1993 or earlier won't have that problem.  This assumes use of a cable clutch system.

The car does not have power steering or any other option for that matter unfortunately.  Although I do want to purchase the MS pedal kit with brake booster capabilities along with the clutch cable kit. 

The bellhousing provided with the trans for sale is from the v6 as well as the flywheel and clutch.  The flywheel I'm guessing I can't use bc of the balance issue. so if I go this route what flywheel do I need? and will the v6 clutch kit work? 

fyi  I found the 03 t5 with flywheel, v6 bellhousing and  clutch kit from a wrecked car for 300.00 and I have is a complete 4 cyl. trans that was mated to my 302.
