The cone-type SG unit usually found in the 489 has a one-piece thrust block, the earlier clutch-type SG has the two-piece thrust buttons.


I'm supposed to respect my elders, but its getting harder and harder for me to find one now.

Sounds like the shim one installs in a used up cone unit to eek a little more life out of it because they are technically not rebuildable. Do yourself a favor and epoxy a couple magnets below the oil level off to the sides of the ring gear to catch the metal chips that POS is going to make everytime you take a corner .

You will need the thrust spacer in there to set axle end play on a stock setup. Or you could install the greeen bearings on the axles and then you can throw the thrust spacer's away. Ron
