Mike,
For the 1/2 ton.
From the pedal (the part you step on) to the first bend, is a little less than 90 degrees, its about 6 3/4 inches.
From the bend to the bushing is about 11 3/4 inches.
Bushing to the hook is about 2 1/2 inches.
Length of bushing is 1 1/2 inches.
Not sure what you'r trying to do, but I agree with John.
