Yeah that sounds like it the t56.

Probably just stick with the t5 as they are hard enough to find

My son and I put in a Tremec TKO 600 into his 66, We have not gotten the car off the stands yet, but it was an easy install, stricly a bolt in deal with the shifterhole being slightly enlarged toward the passenger side being the only modification of the car needed. (about 1").

We did this with a new trany, new rear x-member, and a lakewood scattershield that was specifly designed for this swap.

We are also using the above mentioned Mustang Steve cable setup.

About $1,900 for the trany
$350 for scattershield, (alum bell housing is available from mustangs unlimited for about 1/2 cost)
$350 for clutch assy. + $20.00 for fork, +$15 for "ball stud"
$200 Clutch cable setup.

I ordered the TKO with a standard 10 Spline input shaft so that I would have more "standard" clutches available = cheaper clutch parts.

If you decide to go the "new" route, I highly recomend the TKO 600, as it has a 600lb torque rating, unless you are building a real hoss, it will work without modification or upgrade. Just choose your parts carefully, there are lots of variables.

I know there are several folks on here who have done the T56 swap, I am sure that you will get plenty of help if this is the route you choose.

 

Hey man I just did this on my Fastback, you want to get you a rebuilt T-5 or new don't wasn't your time if it isn't. Then you need a T-5 cable clutch linkage conversion. Make sure you get one that is in conjunction with a late model (1980-1993) T5 type bell housing and throw out arm. Also make sure you get the right year they are different from 65-66 and 57-68. You will also need a T5 transmission crossmember w/ the parking brake bracket. Don't forget the fulcrum & spacer block kit. It sounds like alot of work but it really isn't that bad. Those parts a just mentioned to you are only about $400 all together. Check out this place called California Pony Cars the number is 1-888-225-7669 give them a call they will send you out a catalog.

 

i Did my swap for about 450$ total, with home fabrication, a T5 from a buddys garage for 125$ with 60k miles, junkyard 2000+ clutch pedal/brake pedal, all my own fabrication of supports for that and the transupport, and a new king cobra clutch and plate. I love it! With my 4.11's it was to much for highways, so i went to my 3.73's and i love it! Cruises highway good. Also, Ive driven it REALLY hard and it has yet to break**knock on wood**-Jon
