I've been collecting and stashing away all kinds of hot rod parts for so long, that now that its time to use them,,,,,I can't remember where I even got them from. [oldtimers?]
With 4 months before SPEEDWEEK, I'm nowhere near ready and need to make every turn of the bolt count. I dug these two different 'posi' units out, but don't know which to use? Can anybody look at these, and tell me what I've got. Which one/type is better/stronger?
Both are 'POSI' and both are 31 spline.
The one on the left has semi-counter sunk ring gear bolts. I can't really get a socket on the bolt?
It also has 2 phillip head bolts holding it together
the one on the right has 3 straight screw head bolts holding it together, and seems to have a 'machined' surface on the ring gear side [more than the one on the left]
thanks RICK
