if it is on the adjustable side that is not likely the case because there can't be a nut on the inside. As far as the other end that doesn't adjust then it is unlikely there too (how would one install said nut?). If it is on the unadjustable side I would take it out then goober it all up with 5200 and then put it back on and put one or two small sheet metals screws in it. as far as the adjustable side, i already said what I did.
hope this helps. i think i am better at working on these boats than sailing them
