Rear shock lengths/suspension travel

I did some measuring up around the rear suspension today. The JB +2" springs are 13.5" long and around 4.9" fully compressed. With the axle up against the bump stops there should be at least 5" of distance between the top and bottom spring lengths so no bump stop mods should be needed. Dropping the axle down to give 14" between seats the distance between the shock eyes is 22", the extended length of my +3" BJ supplied Rough Country shocks is 21.5" so that looks OK and will give almost max. travel without the spring dislocating.
With the axle up against the bump stops there will be around 12 3/4" between shock eyes which could be an issue because the compressed length of the shock will be 13". I'll have to measure that a bit more accurately, I may need to add 3/4" spacer to the bump stop or if the shock seems a bit hard to relocate the top mount.
The one issue that I do have is the panhard bracket which hits the chassis just as the axle hits the bump stop and prevents the bump stop from compressing so I reckon I'll be switching to adjustable panhards.
