yes, don't worry marin fitted those ones, occasionally the 'wrong' way too. any decent 122mm bb will be ok, UN26 also good. un26 will do the job but, look for a un fifty-something for longevity. just fit as normal, main body on crank side and cup on other side. just make sure you buy 'english thread'.
Any shimano UN something or suntour will be ok if you have jis/campag concerns(those are different taper-wise) even those RPM ones seem ok.
