Swapping a five-speed manual transmission into a vintage Mustang is apopular resto-modification for many enthusiasts. In fact, we imaginehundreds of you have already performed the swap. Of all themodifications you can do to an early Mustang to improve its fun-to-drivequotient, we think this is the single best upgrade you canincorporate--especially if you want to turn a car into a truly viablehigh-speed, long-distance touring machine.
Which would you rather do--drive on the highway in Fourth gear at2,600-3,000 rpm, or drop into Fifth at 1,800-2,200 rpm? It's an easyanswer for us. Any regularly street-driven vintage Mustang with anautomatic benefits greatly from an AOD, and any stick-equipped car doesthe same with a five-speed.
There are several ways to go if you desire a five-speed manual in your'65-'73 Mustang. That's why we thought a review of the process and astep-by-step look at the method we chose were in order. With a T5, youcan use a late-model T5 bellhousing along with a cable clutch linkageconversion kit, or you can use the car's existing four-speed bellhousingand run an adapter plate to join it with a T5. In the case of oursubject car, we went with the latter.
The conversion shown here was done on a '69 fastback equipped with a351W and a Top Loader four-speed. If your car already has a manualtransmission, you can procure the parts for the swap from CaliforniaPony Cars. As for the transmission itself, National Drivetrain is anexcellent resource, with its Platinum Torque line of rebuilttransmissions, including the venerable T5 five-speed, as used in someform or another in Fox-body/SN-95 5.0s from 1983-1995. We've alreadydriven the car extensively with the Platinum Torque T5 in place, and itshifts and functions as new. What's more, there's a full one-yearwarranty included, and you'll save about $200 over the cost of acomparable brand-new T5.
Any vintage Mustang with a 260/289/302 or 351W small-block can be fittedwith the same components we used to get this '69 SportsRoofcross-country worthy.
