I hate to be this guy but I only have access to a shop for 3 days to do my 4wd swap which includes a 271 case swap. Would anyone that has a 271 swap with a nv4500 be willing to go measure the rear driveshaft and tell me what I need to have it cut too? I already bought the flange I'm just trying to make it drive out n be prepared for when I go in. Thank you to whoever can do it!! It would really be appreciated!
