Great Tool
I found MBS MFG after watching YouTube videos about changing the gimbal bearing with their tooling. The reviewer was very pleased with the product and it’s quality. I decided to order one based on this. Much to my surprise, it was shipped the same day as ordering it. Received pack really well. I’m very happy with the tooling, the fit is perfect and the lack of black coating is a great plus! Finished the job the same day I received it. We’ll made, shipped quick and priced right means a successful and happy customer!! Thank you MBS!!
