1972 20' SF Leaning post?

[waterboy]

Hi gents. I purchased a 1972 20' SF a few months ago and have been adding stuff to her to make her more comfortable. First off it didn't come with any type of console seating so I've been using my 105qt Yeti as a seat which to say the least is less then comfortable. Which brings me to my question. What leaning post (Rocket Luancher) with back rest, preferably w/ a removable backrest, do you guys recommend? A buddy of mine said not to do one as it took up a lot of room in the rear of the boat? Told him it was a leaning post or a cooler with a backrest. He had no comment as he is a hardcore fishing guy and would probably have a live well set there. Thanks in advance for any advice.

Edit: Can't post pics as of now because I'm stuck in the D.R. and the internet is skechy. But I will post some pics of the boat when I can.
