As I do realize 5/8" studs are good insurance, I neglected to opt for them when I purchased a complete S-60 rear from Strange Engineering a while ago. Wouldn't be such an issue but understand these axles are hard on drills and taps and told best to box up and send back to Strange Eng. It currently has 1/2" studs. Vehicle should weigh 25-2700lbs, around 800hp/ and transbrake w/2.45 1st gear. what do you think. Does anyone know of a reputable place in central Florida that is fully capable of performing this work? Thanks, Bill
