I'm just sitting here thinking, and hoping I'm posting this in the right spot, I recently got a 89 k3500 srw with a 454, it's gvwr according to the title is 8600, from what I have seen I thought the k2500 8 lugs were 8600 and k3500 were 9200 so whats the difference if any, also mine has a dana 70hd rear end rather than the 14 bolt, is that good or bad, one more thing, I haven't measured it but the frame looks the same as my k1500, is there any difference in the frames of the c/k series, sorry for the long winded post, just curious.
