Wasn't sure if you were aware of this...
I was installing the rear 8.8 into my ZJ this weekend...and I ended up having to grind away quite a bit of material off the shock mounting brackets. The flange was too narrow and contacted the body of the shock, or the hole in the flange was drilled too far into the bracket and caused the interference. Eitherway I was able to over come the issue at hand and install the rear, however I thought you may want to know.
This was a Rancho gas shock I got from Nick at Kolak...standard issue shock I believe.
Overall, the product is Kick@ss and everyone compliments the ridiculousness of strength it provides.
