How do you install a spool in a car that has a posi?
My posi is CRAP. I don't drive this car on the street a whole lot, so a spool would be a nice cheap solution. Since the posi is also the carrier, how would you install a mini-spool on a car with a stock posi such as my 88 bird??

Just put a nice bead in the valley of one tooth on each spider, it'll lock just like a spool.

Well, I'll admit I haven't seen anybody do it for a little over 30 years. In that case, it wasn't the welds that had a problem but the driveshaft that suddenly couldn't handle the new-found traction (5000 RPM launches probably didn't help, either).
But, if he has to buy a different carrier to install the mini-spool, it'll be a lot more than $50. And, the only ones I see are Richmond & Summit for 26-spline axles only, and cost closer to $100. And, they are for dirt track use only, not drag racing.
Full spool is a different matter. But, don't see anybody that offers them for 7.5/7.625".
Ever tell you about the guy that made his open carrier into a "posi" by stuffing in extra spider shims?
Never mind. If you're changing carriers, either get a posi, or an open into which you put a PowerTrax.

Any street driving at all, and it would probably weld the spiders together for you 
It's not a good thing.
