I have the wilwood 1" bore tandem master cylinder in my BJ7 combined
with four pot front calipers and rear discs. It is a straight bolt in
fit and easy to plumb but the pedal pressure is high. I would recomend
a 7/8 bore. I am fitting a tandem brake booster over the winter so we
will see what the pedal pressure is like then,
cheers
