#34 has Cleveland brakes as Jim did not like the Matco brakes available at the time and as I recall had a set of Cleveland brakes on hand. Subsequently the F1 kits at some point came with Grove master cylinders, wheels and dual piston brakes which is what I have on mine.
Thank you very much! That helps, your elevator is still a work of art and no cracks with the recent SB! Now the question is would they be 66-105 or 66-106 pads.
