Did I do this 8 3/4 housing/axels from moser right?

Too late now but;
I wouldda just put a posi in the 7.25/ so-called glass rear, and run it; you can't hardly kill them with a 318 auto,, even with a 2800 stall.. It's the peg-legging one-wheel peels that get them, and/or the shock of popping the clutch with a manual trans and fat-tires..
Well, The first one broke when going around curved corner (not even a hard right turn) at 25 mph with my foot off the gas. The second one broke after backing out of the driveway, coming to a full stop to switch to drive stepping on the gas lightly since the wheels were still turned and the spiders shattered again.

Pretty much done with 7.25's. The car never did burnouts because it can't even break a skinny tire loose unless it was going around a corner and I very seldom did that. In other words, none were abused, they just broke. Maybe others have had better luck with them? The 2.73's? In there were just not gonna be what I wanted really anyway. I will have a spare to drop at a swap meet sometime. I'll make sure I tell the buyer about the howl in the one that's in there now.

Thanks AJ. I've learned a lot reading all your stuff, especially on dynamic compression ratios.
