Both the ones at rock auto are for a 3100 it says. Mine's a 3600, the ones I bought were the only ones I could find that specifically said 3/4 ton. I may have paid too much, but do those at rock auto work for a 3600? I'd really appreciate some help with my situation, or if I could get some suggestions or if you know for sure another brand/seller works without the issues I described that'd be good too.
