53 Rear End

I Have A 53 Chevy And Wanted To Know...is It Possible To Convert Stock Rear End And Driveline To An Open Setup With Stock 3 Speed. Second Question...do 53 And 54 Run The Same Rear End? The Reason I Ask Is Because Someone Gave Me A 54 Rear End And I Was Thinking Of Rebuilding The 54 And Then Just Swapping It In. Thank For Any Help.

 

I'm sure it's possible,,,but you will spend a lot of money on that free axle,,,HRP
