I got a rear end from a swap meet and iam trying
to figure out what i got. I sand blasted it today
and these are the #s I found. K174 and GM4 and
HA12 and 3856525 it is 62" from the outside of
the drum to the outside of the drum. its a 12
bolt. and has 6 lug. I did a search but could
not find any help. searched the net and found one
sit that I found one of the #s. it was the GM4 #
rpo# it was a 3.67 gear ratio. but it said this
number was found in the drivers manual. so that is what Iam try to find the gear ratio. and what
it came from? thanks for any help.
