my 69 chevelle build

[SS Shaun]

so today i had about an hour to kill so i went to the garage to check on my rear end i wanted to find out what i had for sure. so i popped the cover off and here is what i found



4.11 gears with a Spool but then i found this


they are axles that can handle over 500ft tq so i think i will be good with these axles when i get the posi rear


so tomorrow if i can find another hour i will pull out the axle on one side and count the splines on my axle so i can order my new posi rear
