    30790 is rated 4.0 out of 5 by 4.
    Rated 3 out of 5 by from Quality pieces. Very nicely made! Countersunk holes and the bolts to go with them were perfect! The reason for the 3 stars and not five, why would you leave the hole so small! I understand porting to your personal exact size, but why start at an inch hole. Just saying.

    What are the bolt hole dimensions on both the center bottom holes and the outer tube flanges. Stahl is suppose to be 4.5 in on the center plate and Hooker is 4.25 in. With out exact measurements for the product listed it would be hard to order. I need 4.5

    Asked by: Earl
    The 555-30790 adapter plate has a measurement of 4.916 on the center plate, bottom holes. The outer flanges would measure 2.282.
