10" vs 11" brake hubs

[62savoyguy2]

Have 10" brakes on the front of my 64 Polara. I have a pair of backing plates and drums that are 11" off a 69 GTX. Are the hubs the same on 10 and 11? Have extra hubs I am going to use. Thanks in advance......

I came up with this information in a November 2005 NAPA Bearing and Oil seals number book. The 10" and 11" hubs take the same number inner and outer bearings, which are BR2 outer, and BR6 inner bearings. On the inner seal, book is saying the 10" spindle requires seal number 17115, and the 11" seal is 17110. I've had many of these assemblies apart over the years, and never visually noticed the spindle between 10 vs 11" that it is different. But I have never measured the seal area, with a mic either. I'll almost bet, these two seals, are close to being identical. Please do your own homework beforehand, just to be 100% for sure. Hope this helps you some.

No they are not the same. The offset is about 1/4" difference on the two flanges .
