The eternal quest for wheels. Can you let me know the model number for the etrailer/dexstar 16x6 8 lugs? I was on the phone with etrailer and asked them about the back space dimension. They called Dexstar and the guy at their plant measured 4" for the back space. everything i've read in this forum is telling me i need to keep the back space to 3.5-3.75" for my '51 GMC 150 to clear the tie rod ends. I'm a little cornfused.
