Equa Loc is the early clutch style posi Ford used before it introduced the Trac Loc. They are very similar but they don't interchange parts. Externally they look very similar as they both use a cast clutch cover. The EL uses 5 tab steels, 3 friction disks and a belleville spring to preload the clutches/steels. The TL uses 4 tab steels, 4 friction disks and four small coil springs to preload the clutches/steels. The hubs that the frictions ride on don't interchange either. I have a good photo of the EL which I will try and get hosted somewhere.
Randy's Ring and Pinion sells the clutches for the EL. They also show up on EBay periodically.
