This is a new reproduction brake pedal arm. These are the ones that are always worn out when found and will make the pedal wobble back and forth. This will fit the MB, GPW, CJ2A, CJ3A, CJ3B, M38, and M38A1. It is also a good idea to replace the idler shaft these ride on as well.
NOTE: These will sometimes need to be honed just a tiny bit and or the paint cleaned out of the large hole for the idler arm to fit snugly.
