Hi,

I'm rebuilding my 9 inch rearend and it has the big bearing end. It's originally from a 1967 Bronco.

Does anyone know where I might find either:

- 10" backing plate for big bearing end
- 11" x 2" brake drum with 4.5" bolt pattern?

Go to ebay for the brake backing plates, usually small and medium size cars have the small bearing while trucks and big cars (like Galaxy) had large bearing, but that is not a hard & fast rule, you have to check each year and application specifically.

As far as the brake drum, that has to match the bolt pattern of your axle, so unless you are putting in axles with 5 on 4.5 then its not going to work.

And I have to ask, why 10 inch backing plates if you are going to use 11 inch drums?

Hi,

I've been browsing eBay without luck, I need to know if there's a chance I can part either of these two things from a car. I prefer an 11" drum with 4.5x5" bolt pattern (not 5x5" as most 11" drum have) because I already have 11" backing plate. However there are not as many wheels available for the 5x5" bolt battern with the back spacing I need, I have Moser axles with 5x4.5" bolt pattern.

Option two is to buy 10" drums with 4.5" pattern and all hardware and of course a 10" backing plate for the big bearing end, just need to find it.

Can anyone point me in the right direction?

Do you guys probably think the best way would maybe just redrilling the drums with the 5x4.5" bolt pattern?

Ok, so buy drums for a Ford "big car" that has 11 inch brakes (example 1970 Galaxy with big block). The wheel lug pattern will be 5 on 4.5.
