on my build sheet for my 84 Trans Am it says it has a WY6 suspension package. I bought a parts cars (88 Formula) that had WS6 suspension. the sway bar was def bigger on the Formula w/WS6 but the brakes, knuckles, contlro arms, panhard bar, etc were all the exact same size parts. is the WY6 basically a WS6 suspension except for the front sway bar??

 

Maybe its WW6? WY6 is not a valid RPO code. The WW6 is an appearance package - the "aero" package.

 

WY6 indicates that it has the WS6 without the posi rearend.
