I have been debating on a new rear for my car.

I need to know first what are the signs of a rear going? I've swapped them out, etc, but never driven a vehicle while one was going on itself.

The reason i ask is my 70 nova (stock 10bolt) used to spin the left tire the fastest when on jack stands, or doing a burnout. Now for some reason, the right wheel is the quicker one, it burns out, etc. It's swapping back and forth. My friend said it's a sign of rear end failure. Is this true?

My biggest holdup on a new rear is this.

Do i want a spool, a posi-locker, or should i weld my axle/spidergears together?

I've been qouted $150 to get them welded together. I know i'll eat through tires quicker because they will ALWAYS spin at the same speed, even in curves, but other than that, and the fact i'll slide through curves, what are the other things i'll experience from getting them welded together?

The welding idea is deifantely the cheapest. $150. The posi will have to be bought, then installed, and will probably be more towards the $500 + range. The minispool is "only for circletrack use" ...so what do you guys think?

This is a daily driver for now (but not for too much longer) but it will be street driven 3 days a week at least.
