an adjustable track bar will still require the OME or like relocation bracket to prevent the track bar from prying the bracket off the axle. I couldn't even beging to tell how many I've fixed or how many people will argue about it.
JKS rear adjustable shown....
any shock longer than stock requires the use of at least 1.25" rear bumpstop extensions, which is the amount needed to prevent the bracket from hitting the tub.
an angle drill is not needed with the shocks and track bar end unbolted, the axle hangs plently low.
