Track bar drop bracket measurement

[4.3LXJ]

I thought you had the bracket in hand. Not much I can tell you then if they won't supply you the info. But this would be worth a try. If I was building one I would use the same bushing as the other end. In which case the measurements would be the same as for the axle end of the track bar. Ask them about the replacement bushings for the track bar and if they are the same on both ends
