JEGS 4-Link Suspension Kit [4130 Chromoly Tubing and 5/8 in. Tube Inserts

Purchased original set in January, Welded subframe in car per instructions in 4 link kit. Kit instructions state 21” center to center on rod ends for 4 link bars. 4 link rods are 1” to short to achieve 21”. Link rods were black pipe not chrome moly. Axle link brackets looked like they were cut out with acetylene torch. Returned kit, took a month to get new kit. New kit looked much better, plates cut out on plasma table. Rod ends were chrome moly this time but still 1” to short to achieve the specified 21” per the 4 link kit instructions and the bolts that are supplied in the kit are corse thread and all the nuts are fine thread so I can't use them either. I was informed, that's the way the kit is assembled. So change your instructions to state that the rods need to be 20” center to center so the next guy doesn't have to cut the newly welded back end out his car for your poor instructions please. Or put the correct size rods in the kit to start with.
