I still have the 8&3/4 under the valiant, with who know's how many passas, this year I'm going to start beating on it hard with the trans break. I have beefed up the caps, and installed some moly bolts in them, and still have the crush sleave, the housing has a backbrace and the ladder bar mounts are tied in to the shockmounts and backbrace, the housing is the problem for me, I have bent the housing more then anything else.
I have the 489 case with a spool and moser axels, and 4.30 street gears.
