From what I've read, the 1956 big bearing 9" rear I have should have a 2.36" offset. I just went out into the shop to double check and... Came up with 2"?? What am I missing here? I measured from front of axle housing to front of wheel mounting surface.

I believe that the measurement is to the axle housing's flange. You have the backing plate and retainer plate in the way.

Doh! I thought that the plate I was measuring to was the axle housing - thought that the drum backing plate bolted on from behind.

Well, you are working with a 64 year old housing so no telling what could be forgotten or go wrong! See what happens when you're "forced" to stay home?

Here’s a good video from Baer that shows how to do it, too.

So now I'm curious, what does one do with this measurement?
One uses this measurement to make sure that they're buying the right brakes for their rear end :)

Green67 - thanks, confirms that the offset is 2.36"! I imagine that mine is the same as there's no way that the backing plate and the retainer can be 1/2" thick collectively... so it must be the 2.36" as well.

Yeah. I’ve gone down some of the roads as you. I just got the rearend and planned to use the 11x2.5 drums. Then realized there are few available. I did find one source at $100 a drum. Then thought by the time rebuild these I should look at disc options. I found there are less options available in big bearing old style ends. I’m thinking of going to older galaxy drums wich I believe are bolt on and drums are cheaper.

Ha! Mine came with 11x2" drums... even more oddball. They are hard to find and pricey indeed.

I just bought a set of Wilwood 11" rear discs for a big bearing Ford rear end off Amazon for $650 - I will post a thread when I install them! I hope that they will bolt up pretty quickly and, with a new MC, end my braking woes once and for all.

Kelly, I didn't realize you and Jane had braking issues. Are you planning anything fun, or just upgrading to end trouble and have nicer than before ? LSG
