8 3/4 pumpkin 741 case - 3.23 SG

Why don't you just add a sure grip to yours? All you need are bearings and a dial indicator to set drive gear and pinion backlash.
Mopar 8 3/4" (8.75) Clutch Type Sure-Grip ("Powr-lok")
1- I have no use for a 741 case. 2- it came out of a 340 duster that I restored and had the wrong 3rd member and it’s been under my bench for years I’ll never use it! If I wanted to make it a posi I would’ve a long time ago. Plus that pumpkin wouldn’t hold up to the kind of driving I do specially with a 4spd.
