[quote=tamumpower1]The end caps are held on by the dolphin striker nuts. Most likely they are stuck on there pretty good and take some nice oil and banging with a mallet to remove. Not sure exactly what you are asking with the whole square up the casting with the hole thing. The inner hull bolt should be an allen bolt that threads into an insert with a helicoil in it thats riveted in place. The outer bolt is just a hex bolt and nut through the lip. If the holes don't line up then just loosen the inner and outer hull bolts and move the whole beam so you can get the bolt in. You don't need to adjust the end caps as long as they are all the way on...
If you use an extension the dolphin striker shouldn't be in the way and for sure you don't remove it to mess with the beam bolts.[/quote]
