I have a 67 Skylark I plan to restore and drag out at our local track. It currently has the stock rearend. I'm goingt o be putting a built chevy 350 in it and witehr a th-350 or 400 tranny. For ther rearend I was advised to go locking rather than posi, but not sure where to go from here. Any suggestions on how to takle lockers? o No: Can I keep the current axel and throw a locker kit in it or am I better off swaping in a differnt axel?
