Rear suspension problems

[skag101]

This may be a tough one. I have a 1998 30ft. Windsport. On the rear suspension there is a sway bar, and there are large rubber bushings ( thats what I am calling them) that connect the sway bar to the leaf spring hanger. there are two on each side. I have been to several truck parts dealers in my area and no one has seen this before. Seems to be something added by Thor possibly.
Anyway, one of these rubber pieces has sheared in half due to age and getting hard. Does anyone have any idea what I am talking about, what this is called, and where I could look for this part? This one has really got me stumped. Any help will be greatly appreciated.

If your coach is on a Ford Chassis have you gone to Ford parts, entered your VIN and searched the chassis and suspension parts?

Chevy chassis.

Talked to a mechanic where I work which uses delivery trucks on the same chassis and there is nothing like this on their trucks.
