I have a 1970 Mercruiser 120 stern drive pre-alpha unit with the trim limit switch on top portion of gimbal ring. The bellhousing has the side pins that you need a slide hammer to remove and the nylon-type washers that go in between the housing and gimbal ring. I just noticed that the bellhousing has up and down play. I would like to know if there are oversized pins available or some type of aftermarket bushings/sleeves to insert in bellhousing to tighten everything up. I really do not want to replace the bellhousing. I keep it well greased, but it still has play. No cracks noted. I could not find anywhere in any forum addressing this issue. Thanks.
