Perfectly good starter
Style: S114-823S
Though I'm sure this was a good starter it looked great I'm sure it would have worked perfectly however because of some problems with my engine and bolts being stripped out in my motor I had to return it but there was nothing wrong with the starter just wouldn't fit
