the rubber boots i replaced are at the ends of the shift transfer rods that go side to side . these rods transfer the shift command from the hand held shifter to the shifter on t case and trans.
that is the only boot i am familiar with. i guess i'm not much help at all.
unless you can be a bit more specific and it stops raining here long enough for me to crawl under and look at mine to see if i cant be more help.
