building 8 3/4 489 section

IMO 8 3/4's are good rears and there are thousands of fast cars running plenty of power running them. I've only heard of a few ever breaking on the street in the 40 years I've been messing with them, mainly because there isn't enough bite on a public road.

I have a 8 3/4 center with a spool and 4.57 gear that came out of a friends Duster that ran 7.70's (1/8) if you're interested.
