mamiya rb67 flash?!?!?

i know this is a pentax forum but someone might know the answer. my problem is that i have a 90mm lens that wont fire the flash when connected to the x plug via pc cable, also i have a 37mm which fires slow on the 1 second exposure setting ie half way through the 1 second exposure the flash fires. are these problems fixable? are they hard to fix? or am i sol?

How good a fit is the connection? My PC cable does not fit my Pentax 6x7 very tight and often does not fire. My Hasselblad lenses has a locking feature for the PC cable, fits snug and fires every time.

solid connection, i found out how to fire the 90mm. i have to force the lever down hard for it to cock the lens all the way i guess.
