will this fit my 2020 kubota 95svl? thanks

No.  It says attachment side.  You want the machine side.  CLICK HERE

I have a 2017 Case TR310. Will this dust cover work with my machine?

No.  This is for the attachment side as the heading states.

Will this end cap fit my cat 289D aux electrical hook up? I lost my cap (on the track loader arm itself). Thanks.

I have a bobcat snow blower that has either a 7 pin ( which we use) or a 14 pin option. I'm making sure this dust cap will work to cover the 14 pin female end. Thx Kevin

Yes.  Correct.

When will you get this item in again?

These should be in stock.  Will adjust the inventory now so you can order now.
