8 1/4 axle 11" drums

Thanks guys for the info. The drums do say max dia. 11.08 on them. The axle is the right length for a A body and the perches are in the right spot. someone probably did the 11" up grade. I got the axle for fifty bucks and Iam picking up a posi unit an 3.91 gears from the guy for 150. this weekend ;) I cant wait to get in my car. which has a 8" ford in it now :(
