Limited slip diff

Hey guys does anyone know what limited slip rear ends will work on these cars? Specifically my 67.

Good used 8" Trac-Lock units are unobtanium and probably shot if you did find one. Have a 'L' stamped with the ring gear ratio on the carrier tag.
Yukon & Detroit both sell new units that will set you back around $500.

I hear the true trac is the way to go, don’t have to worry about the clutches wearing out. I wasn’t concerned about that when I got the tracloc, it’s just a cruiser, don’t plan on thrashing it toooo bad.

Not discriminating between 8" & 9 ":

59.25 1967-1970 Mustang
59.25 1967-1970 Mustang, Fairlane, Comet, Cougar
59.25 1967-1971 Comet, Cougar, Mustang, Fairlane
59.25, 61.25 1967-1973 Torino, Ranchero, Fairlane
59.25, 61.25 1967-1973 Mustang, Torino, Ranchero, Fairlane

1-2 inches is easy to accommodate with all the wheel offsets these days (or if you're not looking for widest tire - doesn't so much matter).
'cause Johno says you gotta have a sig pic! :)
