Take a look under the toe rail
Kevin - since you have an early 90s vintage boat that means they had the extruded aluminum toe rail. The pulpits, pushpits, and stantions had bolts spot welded to the inside of the stainless tubing and the threaded end went through a hole drilled through the toe rail extrusion. Therefore.... look under the toe rail and you'll see a nut at each tube location. Remove the nuts at each point and then the item can be removed (the stantions of course have a couple screws into the deck that need to be removed too).The pulpit and one of the pushpit halves have wires for the running lights so be careful when removing that you remove the wires and not tear them out.For reassembly I'd recommend applying some lanocote to the threads, the nut/washer, and to the stainless tube where it contacts the aluminum to minimize galvanic corrosion.Also, for that age of boat it wouldn't hurt to install new wiring for the running lights too, starting at the splice in the chain locker. Look under the deck inside the chain locker for the wiring - thats probably where it is (not familiar with your boat model so can't promise).Hope this helps.
