Moving Rear End Back 1"

Thanks for the input fellas. For now I just put a set of perches on with three holes and moved it to the back hole. Left plates and hangers alone. Ubolt angle isn't drastic since I'm using taller perches than stock and 1 1/4 lowering blocks. I like that it left my shock mounting in the factory position. If it doesn't work out then I will move back to the center hole on perch and space the hangers back.
