got a chance to crawl around under this '68 barracuda that's had a 383 and 4 spd put in - Number on diff. case is 2881489 which I've read are '69 and up. sound correct? Also had a small tag-like piece under that with what looked like 465710A . Is that telling me anything? Not 100% yet if this sure-grip. I found 2 bolts on top of housing that are not torqued down - probably sounds ridiculous but is there any reason they should not be? appreciate any comments. thanks

The two bolts on top are probably for a pinion snubber. Only way to check for suregrip is jack the axle up and spin a tire. Both spin same direction, suregrip. One spins opposite direction, open.
yes, exactly, thanks. Found a diagram and those appear to hold optional bracket or snubber. I can tighten them down to keep them around. It was a brief wtf moment, for me anyway!
Supposedly it's 3.23 with posi. Still getting broken in so not going lay any strips..

Yes they started using the 489 case in 69 so it must not be original. Not sure what the other numbers are
thanks for response - jacked up rear and they spin same direction so they should spin the same direction when I wake my neighbors up.. When I tighten those bolts down I'll add some washers as spacers if it looks like they go too far into the housing though not likely I suppose..
