I am about to order the 9" moser housing/axle package, and it shows I can get either 1/2" or 7/16" studs. Is that talking about the studs in the axles. If so, does it matter which ones I get? Because I don't want to get the wrong one and I can't screw my lugnuts back on. Or could they possibly both fit my lugnuts and the 1/2" or 7/16" part is just the part that screws into the axle? Hope I didn't make that to confusing. Thanks for any help.

 

Stock lug nuts are metric, I believe 12mm with 1.25mm pitch (verify!). See if they have a metric option.
