Yep, the very rearward mount tubes need to be cut down to something like 4.5" or something. These are the mounts at the very end of the cab, or right under your back area.set of energy suspension i got for my 73-80 frame pickup truck said you need to cut down the factory tube on some positions to let it fit and tighten up. cant recall now its been 3 years.
Sounds like someone else did a job on the mounts before and got them mixed up.I just ended up cutting the factory sleeve. And as to the comment from that k30 guy, those are the ones that were on the core support. Whether some previous owner moved them, who knows. Good ol sawzall fixes all problems:-)
