I'm going to be bolting a 9" differential into the '88 and need some help on putting together a parts list for it's center section.

Should I use a Posi-traction unit or a Mini-spool? The car will be primarily street driven but will see the dragstrip a couple times a month. Also, what brand should I look at?

What brand of gears have a good track-record? Or will any of the manufacturer's be fine?

What are the benefits of an aluminum case? Is it worth the extra cost?

What are the benefits of an aluminum pinion support? Worth the extra cost?

What pinion yoke should I go with?

THANKS!
