well had the guy over today to swap out the gears and as i spun the gears in the housing without the axles in it there was this rattle noise.....when he pulled it out of the housing 2 round pins with flat heads fell out.....if i look in where the axles go into the unit there is a hole that runs thru the spider shaft and the axles butt into these when installed
so that was the end of the swap till i find out whats up with that....i looked at a spicer exploded view website and it doesnt show these pins....what i have is a 68-69 high performance powerloc #25124x
