[oletrucks] To punkin or not to punkin

[BLUCHEETAH@aol.com]

Hi guys, 
I'm looking at my '53 Chevy 3100 and underneath I have an open drive line. I 
think that's what it's called when the pumpkin has removable differential 
covers on both sides. Since it is open like this, is it still necessary to 
replace 
the whole rear end when you regear it to go at faster speeds?  I'm really, 
really hoping you will tell me it isn't necessary!!!
