help with new brake cylinder MC1722

i'm lost on how to install the MC1722 master brake cylinder, my original has 3 bolts on both side, the new one has only 2 on each side, the original bracket doesn't fit... I would appreciate input on this and any photos of a completed install, thanks Terry. the unit is a 56-S100...

Terry, The S-100 shows 2 MCs, the only difference is the 3rd hole needs to be drilled and taped, I helped a friend do this on his S-100 years back, his 3 speed linkage bolted to the outside of the MC.
The IH Part Number is 161548R91

i was thinking to do that, the new one bolt center to center is shorter, the cylinder will be mounted on an angle if I do it.

Terry, if you have enough to tap? You can install a spacer or washers to get it straight, or rebuild your old one.

lucked out a friend from Edmonton, Alberta brought me a good used MC, i will use the new one on my next build..
