Good Idea Captain.
I had already tried to find the track bar bushing locally but struck out. New bushings and U-bolts have been ordered from LMC.
Looks like the same track bar bushing was used from 64 to 72 even though the pre 69 bars are longer length as they mount differently on the axle tube .
Looks like I am waiting on parts for this weekend , Hope my backup light parts get here before Friday.
