rear sway bars-OEM- need help identifying the difference

[stevenlee]

I have a '94 with stock 17.5 mm rear sway bar, the one with many bends to go around the cats. I'm looking for a 17.5 mm Zanardi type "straight" rear bar. Gunn Acura lists a 19.1 x 3.0 bar for a '99 Zanardi and a 19.1 x 2.3 bar for a '05 standard NSX. They can't tell me if these bars are the straight type or what the last numbers mean. Does anyone know? Also what year did the 17.5 mm rear Zanardi bar come on and was it the "straight" type?

Thanks in advance for any help!
