Brake Booster Questions Disc Conversion

[fish on]

I swapped a front axle disc setup from a 60 into my 70 FJ55. I had the booster and MC from the 60 for the upgrade also. I went to put the bosster in and it is a different bolt pattern and a support rib on the firewall is in the way. I have done some research and still can't figure out what booster can be paired with another or with the 60 MC and work. Or should I just cut out the rib and proceed with the 60 combo? Or should I buy the adaptor from JT outfitters but will that work with a 60 booster? Oh the agony!!!!

I know people with 40's have cut out that section of firewall and spliced in later 40 series firewall.

Not sure what you would do for a 55!

I am using 60 series booster on my 66 Fj40 (has a rib). I built an adapter similar to this to clear the rib. I am running an 80 series MC.
