Ok, the reason for my question is because my 2000 xls makes a little tapping noise from under floor board so I looked at the pad and isolator they look intact, I also got a hold of some A torsion bars with keys from a 97 and I did see that the 97 keys have a piece of what looks like a piece of radiator hose cut out piece were the keys touch the isolator pad and my 2000 does not, the other question would be is, Can I use the 97 keys onto my 2000? I got it all together and since the little cushion on the keys were worn out on the contact point I took that pad off and cleaned them, so I'd like to remove my bars with keys and replace them with the 97s all complete the way I got them bars and keys together so I don't have to pull out the original keys.
