Dear Welder Series…
On the coil over shock crossmember it shows a 1/2 hole for the lower a-arm, the lower a-arm pivot bushing on my lower a-arm requires a hole 1 3/8 hole. Is that going to work on this crossmember??

Dear Len…
Len, the 1/2″ hole is stock Mustang II. Many aftermarket a-arms use a 5/8″ bolt and some spacers inside and on the back of the crossmember. Depending on the arrangement of your spacer(s) and bolts, the 1/2″ holes might only have to be drilled for the 5/8″ bolt. If the spacer is 1 piece (on the driver and passenger sides), it can either be cut in 2 to put one section between the front and rear crossmember plates and the other piece on the rear side of the crossmember. Or the rear hole can be opened up to the spacer diameter and leave the spacer as 1 piece.

I hope this answers your question.
