Dear Welder Series…
There are 3 holes in the frame for the front fender brace. the (upper) rear hole center is axle centerline. We put the top hole of the Vega steering bracket 10-1/2″ back from that hole and 1-5/8″ down from the top of the frame rail.
However, it is always a good idea to mock up the front suspension parts with the frame at ride height to be sure the drag link is parallel to the tie rod and at the same height and that the drag link tie rod end doesn’t touch the tie rod.
Thanks for asking.
