Default Sway Bar question... HELP!

I looked through my 99 Service Manual and wasn't able to find the answer, so I'll trhow this out to the collective wisdom of the CF membership...

Does anyone know the thicknesses, in inches, of the front and rear anti-roll bars for a 1999 coupe with the stock suspension?

What I'm trying to determine is: Are the front and rear sway bars the same size on a base suspension 1999 coupe, as on a base suspension 2004 coupe? (0.91/ 0.68 diameter)

Thanks in advance.....

Merry Christmas...

Base size for the stock 99 bars was 23mm for the front and 19.1mm for the rear, the optional Z51 front bar was 25.4mm and the rear was 21.7mm.

If you are looking to change the stockers... upgrade info for a few is as follows...

28.6mm, front; 23.6mm, rear --- FE3/Z51 00-04 --- Source
31.75mm, front; 25.4mm, rear --- Hotchkis --- Source
38.4mm, front; 27.5mm, rear --- GM T1 --- Source

I just installed the Hotchkis bars, but my road test will have to wait for spring.

I have the HOTCHKIS now, before it was the base setup. what a difference! It really made the car a lot more fun to drive.
