The Stovebolt Site Forums The Shop Area Driveline HO52 swap out for Dana 60

I picked up a Dana 60 from a 69' F250 with 3.73's. I have it bolted up using it's spring perches but the diff has a slight up angle to it on the driveshaft end. Will this be a problem? Or do I need to modify the spring perches and get the diff driveline to set level. It's on a 49' 3600.
