Anyway, these are some pics of the current layout:
As you can see it is all procell/azek/pvc. It doesn't appear to be that difficult and in fact I may be able to use quite a bit of the current railings. Essentially I will remove the steps from the current location and place them in the middle of the front (that is about an 8ft span. Then cut out 4 ft of railing and move it to the side where the steps currently are. I'll have to buy a couple of posts to anchor each side of what is left of the front railings, and one more to anchor the side.
But I can't see how to disassemble the railings. There are no clips so I thing the top comes off somehow to get at them. People have told me they slide off, but of course I can't do that as they are currently terminated at posts.
So if anybody has any sage advice for this project I would greatly appreciate it.
