Just make sure you get the correct centerlinks for the new bar. Older ones WILL NOT work as it sounds like you already understand.

Luckily I got mine from a member, so I had all the parts I needed. But yes both anti-sway bars (Front and rear) have 2 centerlinks.

Sh**.... I may be wrong.... Bill I think it was 16.0mm dead on... And the rears were between 15.0-15.2mm... Yeah we need a remeasure ;)

I'll re-measure today if I have time. Got a fun night scheduled with a dragster and 6 fuel injectors.

I measured my springs and swaybars again.

Front spring diameter: 16.0 mm
Rear spring diameter: 15.0 mm

Front swaybar diameter: 32.0 mm
Rear swaybar diameter 21.0 mm

Willwren-do those numbers apply for 96-99 also? I'm assuming you have the stiffer of the spring rates.?.

is every part of the spring the same size? so in therory it shouldn't matter where the measurement is taken?

what year and suspension model (RPO) are the largest springs and sways found on?

FE2 and or F41<--- in the 92-99 years this was used in 92-93... I don't think we have seen a 94 yet that had the F41...

Willwren pretty much has the closest to an F41 set up...

Both the F41 and FE2 use the 32mm front sway bar and the 21mm rear sway bar..

The F41 had ever so slightly firmer springs...

Problem though is that there are several spring rates for each code group... FE2 has several, and F41 has several... Sometimes FE2 and F41 springs are listed together...

There is also an FE3<--- This was not used for pontiac...( I think )

If you can get springs at the measurements that Willwren has listed you should have a good riding and handling car...

This is good to know. I will borrow my roommates digital micrometer this weekend and measure both of my bonnevilles saturday.

I would love to know if there is a diffrence between the 2 or your cars... I'm thinking that they should be about identical... But I guess we'll find out... Either way its great info.. ;)
