To identify a 8 3/4 rear;

Stand at the rear bumper and look under....
How many bolts are on the rear cover...
If its zero, then its an 8 3/4.
A good book to have is the Chassis book by MOM MoPar. There, inside are pics & good descriptions, diamentions..>SP> and other usefull info.

68,the casting #'s are on the drivers side of the center section they are the last 3 #'s
741 is a light duty center section and tuff to find new gears for.
742 and 489 are a toss up.these are the heavy duty units
