Dana 20 input gear h vs j shift

[sledhooligan]

Rebuilding a 20 j shift and adding a NWF black box and have a question about the input gear. I bought this case used and it didn't come with one. I found one on Toms but it didn't specify if it was a j or t shift. This is the high side 1:1 gear so I would think that they are the same unless Dana change the tooth pitch when they changed to low side gearing too. Theres alot of info about the jeep 20 gear but I can't find anything on the Ford dana 20.
This is the gear I'm talking about.https://www.tomsbroncoparts.com/product/dana-20-transfer-case-adapter-gear-used

They are all the same, auto, manual, T or J.

Dont put the gear on backwards or the transfercase wont work.
