i keep hearing the gas-a-just ones are a little stiff. I'm thinking about going GR-2 all around. any pictures?

No pictures, but I got 'em and I like 'em just fine. And about $100/4 :)

what is the KIT107 adaptor kit that is needed for the rear???? that seems lame.

If you are using mono-leaf shock plates, an adapter kit is needed, I am not sure if this is the kit you refer to.

I had Gas adjust all the way around, but the rear was too stiff. I replaced only the rear with GR2's and it was much better.

Stock single leaf on a 68.
