S/S Springs w/ B-Body 8-3/4" What Shocks to Use?

Maybe someone w/ access to a chassis manual can take a look for you, but I believe the shocks need to be longer than 28.5" from eye to eye when fully extended to ensure they dont max out during launch. I'd look it up for you, but I'm deployed and don't have access to any of my manuals.

I've never used them, but if your current shocks are not long enough, some people run shock extenders which I believe lengthen the shock 2"-3". All they are is some brackets and bushings that attach to the shock mounts and then to your shocks to make them a little longer. I'd ask others before running them since I don't know how they perform.
