I was gonna get those from SSM and I am not sure if they are 8" or 8.5".
I did go with the ones from Gbody and I know those are 8.25" that's what Brian told me, but I used the SSM 1" taller balljoints. The upper arms do look very similar though. In other words the upper arms from gbody do NOT look like the ones he has pictured on his website they have the same fat shaft as the SSM's.
Only reason I went with Gbody was the package deal with UMI lowers which also came with new end links but I had Brian take off the upper ball joints for a $40 credit. In the package deal the uppers were stock size. I then applied the $40 credit to some HR parts Upper boxed non adjustable rear arms that also came with new rear end ear bushings.
I also was not interested in lowering the front end so I left stock size lower balljoints in place. 1/2" taller lowers would have brought the front down. The longer uppers do not lower the car at all but I am guessing you already know this.

Almost forgot to mention I use the Monroe sensatracs shocks. I recently just pulled the old ones that prolly had 20k on them and replaced them with the same I have had for 20 years brand new in the box sitting in my tool box.
