you can expand your search to use 60 series diffs also. they are the same and more plentiful.
I've got 60 series diffs in MT if you don't find some closer.
you will also need the slip yoke end to match the diff flange.

Thanks for the information ref 60 diffs.
In MN, not Many 40’s here about. What would you want for them? And did not realize I needed the slip yoke. Do you have them too? If so let me know what you need for all.

Thanks

what you need is the companion flange to match the dimensions of the later diffs which are a larger pattern than your current 1972 flanges.
it is easier to get the slip yoke end which will slide into your existing driveshafts and swap the driveshafts so the slip yoke is towards the diff end. that way you have the correct length driveshaft with the correct flanges on each end.
the u joints are different also between early and late.
need a zip code for a shipping guess.
