Swapping a sure grip?

Exactly what I want to hear! and yea I wont tear into them quite yet.

Its a funny story about the 3rd members though. In the 60s my grandpa bought a 66 fury, it had an 83/4 in it, but the rear went out, so he went to a junk yard and got a new 3rd member (the 3.23) and it was originally a 2.76 car. So the speedometer was off, he took those gears out and found another 2.76 set. So he got a spare 2.76 and the 3.23 and put them in the barn, they have been up there since the early 70s. I was talking to him a while ago and he said that he had some. All full of hay but they were pretty clean and turn nicely. Amazing what you can find in old barns! LOL
