A couple of notes on our flanges...they are not oversized units that our competitors sell. Oversized flanges will cause clearance probs with starters, etc. We make the strongest and best fitting flanges in the market. Period. Some of our competitors provide easy-to-break aluminum flanges in the name of "cost reduction"...ill advised!
