well.... emailed Cass. He gave me contact info at Strange Engineering. Got ahold of them today. Got an RMA and shipped my axles off to them. $80 bucks for the 5/8ths machine work. I have the dual pattern 1/2" studs and it sounds like they will add a third pattern being the 5/8ths.
NO they won't add a 3rd bolt pattern. They will re-drill/tap one or both if requested of your existing bolt patterns. Did you request both? did you state which one you wanted?If you do both patterns you have a better choice of wheels , Chevy wheels are always cheeper than Mopar.
