Something old and something new! The basic setup is very simular to what you are used to, 2 plates with holes 8" on center. However, they are 3/8" thick and made from A50 Plate for strength! Thats the old part, and you can buy them just like that if thats what you need. Heres the new, the Side Plate Stiffeners. When using these you completely eliminate all flex between the bushing ends. They are 1/4" A50 cut exactly for 2" DOM at the correct distance for 8" centers. They also allow you to put the setup in a more laidback position to help eliminate any clearance issues you may have and now you can do that since you have eliminated flex between the bars. That is option #2. The last option is that we include the DOM, bushings, sleeves, & bolts. The kit comes to you unwelded so you can add the bars before before you weld on the side plates.
