Response from Gary...
Mark,
Merry Christmas!
The 555-51670 item you purchased from JEGS is correct and will work with your Poly. Yes, all LA stock or SFI balancers interchange with the Poly. -snip- all internally balanced/zero balance LA dampners interchange with your Poly. No need to send yours out for revulcanzining unless you want to.
Keep me posted.
Gary
