I have a 1983 H16 and I want to replace the corner castings. I've sound some new style corner castings but I have a couple of questions. My boat has the 1/2" bolt while I think the new castings take a 3/8". Do people bore out the hole, or do you they use a shim or something inside the pylon?
Next question is in regards to actually getting the casting on. I seem to recall reading that the newer castings were tapered? or are the newer pylon's tapered? Or should I just not be that worried about it?
And final question is do I need to worry about the crossbars at all?
