Question on a Ford 8" rearend

[resin addict]

As I've said before, I took over somebody else's project, he had an 8" Ford rearend already installed (on a '32 Ford Frame), as I'm finishing the frame, I'm going through and making sure everythings in good shape, after disassembling the rear brakes I've discovered that at one time or another, somebody removed the lever's that engage the emergency brakes.
After stopping at my local AutoMasters parts store, they tell me that those parts are to be retained when installing new shoes, and aren't available for purchase (from them).
I need to know what my 8" came out of in order to start tracking down these parts.
Following is a pic. of the tag that was on the rear end...can anybody tell me what I should be looking for and where I should start looking for them? (or direct me to a source where I can decode this...I know the 3.00 is the gear ratio, and the 8 refers to the housing size, but that's it...also - 10" ID drums w/ 1.75 " shoes).
Thanks
