If this thing is not being used for offroading, I would just buy a set of https://www.ruffstuffspecialties.com/catalog/30ALB10.html or https://www.barnes4wd.com/Jeep-TJ-Rear-Lower-Control-Arm-Mounts_p_501.html You really dont need bullet proof mounts if it is going to remain a daily driver for the next year or so...by then you will be into a rock jock 60...
First link is for mounts for a 3" tube; his front axle has 2.5" tubes. Second link is for rear LCA mounts, which don't help on the aforementioned front axle and don't offer the protection necessary.
