BTW that's a mini spool. Nobody makes a full spool for the small 10 bolt.

 

excuse my ignorance, what's the difference between a spool and a mini-spool?

 

I really would like to know also.If im not totally wrong here I think the mini spool has to be intalled into a open differential but I really dont know.Some one shime in

 

I think those mini spools are for a 26 spline axle.

 

Mini spool is installed in an open differential case while the full spool replaces the differential entirely. The Mini spool is not a good idea on the street, they are made more for dirt track racing. They tend to break down and I have heard of them exploding out the back of diff covers.

I had a mini spool in a 8.5 inch ring 4.10 gear that was powered by a big block 455 buick-not stock either. It held up just fine, but thats a different rear end of course. I had to drive slowly around corners or else the tires would bark since they don't unlock, still they weren't to bad on the street. I even drove that thing through the winter. They are pretty cheap so if you blow one, your not out alot of money, unless you destroy the rear
