no offense but you don't have rocks in Florida like we do in the west or even a little further north of you. but if you wanted to Whitey, you could make newer mounts for the tubes and gain probably another 2-3" of shock length on the axle tube. If your mounts were on the bottom edge of the tube and they stradled the ubolt some...
BPE's I consider a temp solution because it cuts about 1/2" to 1" off the upper mount. They call them bar pin eliminators but its still a bar pin and its still fastened in a similar fasion to a stock spring. a few years ago BPE's were a good solution at offering up more shock options because many shock MFG's didn't make every shock with a bar pin option. same goes for those goofy front upper stud style shock mount converter thingy's that let you use the more common eye to eye shocks that were more redily available vs the stock style of bar pin bottom and stud top.
But even bilstein 5150's can be supplied with the stud mount and bar pin type bottoms. same goes for RE monotubes. They come in all flavors and styles.
If you want to raise your lower mounts then something has gotta give. either moving the uppers inboard and doubleing up or putting the uppers through the floor, or some other means of keeping travel.
