McLeod Racing

McLeod is a name synonymous with clutch components and has offered all manner of clutch discs, pressure plates, and other hardware for decades. The company's latest foray is hydraulic clutch actuation kits for various model cars with pre-fabricated mounting parts to make the job easier. McLeod Racing carries a full line of hydraulic release bearings for most any trans application, so if you have a driveline conversion or are building something special, its line of 1300- and 1400-series hydraulic release bearings will work with everything from ZF transaxles found in the Pantera to Top Loader four-speeds to the latest Tremec TKO-series transmissions. Whatever trans you're bolting up to your engine, one of McLeod Racing's hydraulic release bearings will fit it.

Though its lines of hydraulic release bearings, external slaves, and master cylinders have been available for many years, McLeod Racing's new '65-'66 Mustang firewall kit saves a lot of installation hassle by providing a pre-cut and formed mounting bracket for the master cylinder that also doubles as the mounting bracket for the hydraulic fluid remote reservoir. All hardware included makes it easy to connect to the stock clutch pedal as well. Just pair it with the appropriate hardware at the transmission (internal or external slave) and you're in business.

Modern Driveline

Bruce Couture's Modern Driveline is another transmission conversion and hardware company that was born out of Bruce's necessity for quality parts, after he bought another company's product for his own '65 Mustang way back in 1996 to convert his coupe from an auto to a T-5 five-speed. The T-5 five-speed, commonly found in '83-'95 5.0L Mustangs, was starting to take off as a nice conversion for early Mustangs to add a lighter, stronger manual trans with overdrive and Bruce wanted to add one to his coupe. He was less than enthused by what came out of the parts box when it arrived, launching Bruce full steam ahead into Modern Driveline and creating a plethora of conversion kits, upgrades, and more. Modern Driveline's latest is its LF hydraulic clutch kits to complement the company's long standing cable clutch conversion kits it has offered for years.

The cable clutch conversion offered by Modern Driveline has been one of the company's top sellers for years, and there's an easy answer for that—it's easy to install and it works! The kit features a reinforcement bracket that bolts to the firewall, which also locates the clutch cable, requiring a hole to be drilled for cable passage through the firewall (the old clutch rod hole is plugged). The kit is designed for modern five-speed conversions, but with an optional aftermarket bellhousing the cable conversion can be retrofitted to older three- and four-speed transmissions as well.

Modern Driveline's new LF series hydraulic clutch kits can be had with an internal hydraulic release bearing design or with an external slave cylinder design. They both have their merits, with the internal bearing requiring trans removal, yet offering more under car room and the external slave being easier to install but possibly interfering with exhaust or other under car hardware. Both systems use Wilwood master cylinders and Modern-Driveline-designed attaching hardware. The master cylinder mount doubles as a bracket for the cantilever assembly that goes between the firewall and pedal assembly. This ensures proper pedal ratio with the master cylinder mounted in the original clutch pushrod hole location. Modern Driveline also offers reproduction clutch pedals with a unique two-piece assembly (pedal and cross shaft bolt together) for easier underdash assembly.
