Can this sending unit be swapped?

[Texas Don]

Okay GS knowledge base, I need your collective wisdom. I've found a fuel tank sending unit from a 1979 L model. Can I substitute this on my E model? I'm totally clueless about differences in the tanks, if any.

Some parts of the unit are the same, but others are different. Do a comparison on the Alpha website to see differences. There are a number of different parts in these units. What part of your is not working?

The unit has severe rust. The cover for the moving arm can't be removed to refinish it because the tabs are so badly rusted that they will break off the moment they are moved. I have had no luck at finding part numbers for the sending units since they are discontinued and no longer shown on any of the parts fiches that I can access.

May not work properly but will fit. The float arm is different

The Alpha-Sports fishe shows the part numbers. The sending unit arms are different between the N and L model and the gasket is different so I'm thinking the units will not interchange.
