Looks like a rear disc brake conversion bracket. Never see one by these guys, but it's just a bent piece of steel so I'd say it's probably pretty reliable. I believe it's one of the best mods you can do to an early 4 runner or hilux.
they said to use the toacoma calipers but do I use the rotors too Or the chevy ones like everyone else. Does anyone know where the install site or instructions are.
I will try and make some time this weekend to make one up......
These are designed for the late model taco calipers (95 1/2 & newer), the ones with the low pattern. Mostly used during a SAS so you don't have to throw away those expensive front calipers and rotors......
