He's done a great job.
He's been restoring his frame and top and I provided a few tips, but he's gone to the effort to get the CNC data to replicate all the bushings, even the tiny ones on the latch. I had mine redone, but as a one-off by the machinist at my shop. He's gone the extra to document and fabricate sets.
Not cheap, but all made-to-order, not bulk. I test fit on an early '65, '65-'66 (gave him info on the bow #2 changes from eccentric to slot bolt, so two varaints of the set for the change), late '67 and a '68 frames and while not "perfect", and some needed light "convincing" on 40 year old parts, all worked really well on my test jig on the various frames I have.
He was generous enough to donate the set to me for testing in return for my info on convertible tops.
Based on the results, I bought two more for the "spare" frames I have as they are so good. While many of the old bushes are "ok", but show cracking/wear, I figured I'd replace them so the restoration of the frames is complete.
Only source I've seen for these parts, and I was really impressed with them.
If you have a frame apart, with typical damaged bushes, I highly recommend considering these to do it right.... as I have never seen an NOS set...
