I had the same issue ('13 FJC w/ 16" wheels). I kept the Dexter's 1/2" studs but used deep splined nuts. The trailer's spline pattern is different than the Toyota splines but the nuts will work with both the Toyota rims and the trailer rims. In other words, I can use any rim I have on either the FJ or the trailer as long as I keep the Toyota nuts on the FJ and the trailer nuts on the trailer. For me this was much cheaper than finding metric threaded studs and swapping them out.Hello,
My Dexter axle just came in and like you, I want to match my Toyota wheel bolt pattern but, it came in with the incorrect stud size 1/2" diameter. Did you order your axle with different studs, did you change your studs (what did you use?) or did you use different lugs (what did you use)?
Thanks for your help, I have learned a lot from your build.
