I'm thinking about getting a clocking ring for my NP241. My Blazer is a '90 with 1 tons, 1" ORD shackle, and 6" springs. Right now the transfer is lowered about 3/4". Is there anything that I need to know before I do the mod. Will the cross member need to be moved back? Will I need a longer front shaft? Has anyone made a high clearance cross member while doing this mod? Will my CV angle be worse?
