I have put a front brake disc conversion on my 1969 fj 40. The kit came from jtoutfitters. Everything fits right but I cannot find the correct master cylinder. The 70-75 Mc doesn’t work. Any suggestions?

If fits but there is no brakes. And yes, I have bled the whole system many times. Regular, backward, and pressure bled...still no brake pressure. I have used the gap tool on the booster push rod also.What do you mean by "doesn't work"?
More detail is required.
Yes. I did bench bleed. The booster is the recommended one from cityracer. The brake pedal is stock.If there is no air in the system, the only thing left is not enough throw against the master cylinder plunger. This points to the brake pedal throw or the pushrod length.
My experience is it probably is both since without sufficient movent of the master cylinder plunger, the air can't be completely removed.
Do you bench bleed the master before install?
I had my mechanic check it out and he gave up.Yes. I did bench bleed. The booster is the recommended one from cityracer. The brake pedal is stock.
I adjusted the length of the push rod coming from the booster with the recommended gauge. I think there is not enough pressure on the mc also. Is there a special master cylinder for this conversion?Rod between booster and master is the next logical possibility.
Did you use a bracket to move the booster away from the firewall to clear that rib? If so, your OEM pushrod is not going to be long enough and you will need to install a longer one to take up the extra distance of the bracket.
