Hope you have better luck than I did - but after 6 months of search last year, I just bought new seats from ACA. No one seems to sell the current beefier ACA models.
I've ordered a front seat from the factory and was rather pleasantly surprised by the price. No, it's not cheap, but its not crazy money for what it is. It isn't $7600 aluminum gear
For those having done this conversion, what adjustment is added? Farther forward or rearward or both? I’m 6’ and my ankles hurt after an hour of flight from the pedal angle. I need to be back from the panel. 7KCAB built in ‘72.
