GMC 58 Rear swap?
 

Hi i'm planning on changing out the Spicer 45 Diff to a 10 bolt out of a 82 Chevy 4x4 will the drive shaft need to be re-modified or will it still line up has anyone ever put a 10 bolt rear out of a 4X4 in theres. I know the perch's are a little wider than the original axle looks like i will need to drill some holes in the perch's in order for the U-Bolt to hold it in place let me know if theres any other options that i can use to make this swap work...

Cheers Rick
