Tom, the t-bird stuff is a pile of junk and i have not seen an upright in use on a t-bird that din't have worn bushes, there is a kit for t-bird/kit cobras that use sperical bearings but that is expencive too.
i just made a whole bunch of top hat bushes, the top hole is a different size than the bottom, you use two bushes per hole, one from each side and they have a machined 1/2" hole in them, this gives suitable mounts for 1/2" hiems.
note that one long grade 8 bolt will be used through the lower pivots and a tubular spacer will be in between the two pairs of bushes to stop the upright from deforming.
John, thanks for the detail and pics. Very cool indeed.
A little more detail on the lower bushings, please: Were your top hat bushings a clearance fit, interference fit or ? How deep is does each bush go into the hole? Will they be loc-tite'd in place? How thick did you make the brim of the top hats? (or maybe you have a sketch or drawing of the lower bushings you could share?)
jmc14, sorry for highjacking your thread on the bushing topic, but John's approach provides a neat rear toe-control option.
