Re: Rear 11\" drums - Dana 44 vs. AMC 20
I don't believe you will be able to switch the backing plates if you are using a CJ 20. The tube diameter on the Waggy 44 is larger from what I have seen, making the hole and bolt pattern on the backing plate different. The drums may work, but as you said the pattern would be different. Other than the plates an drums I think the shoes, cylinders, etc. are the same. Try looking up the shoes etc. for both vehicles on one of the online parts stores and see if they have the same part numbers. You might try the IFJS site for more info.
