Worked perfect in my 8GCBC with the ALY-8520 alternator. Was having intermittent alternator cut-outs and it was intermittent brushes. Takes about 5 minutes to remove and replace, I did not have to remove alternator from the airplane. Also the part is a major upgrade over the stock brush assembly.

Used this part to repair my ALY-8520 for my Mooney J. Dropped right in and was a perfect fit. Took more time to get it out of the box than to install.
