I had to rebuild mine for the 48,it wasn't to bad,but then i'm not done yet,still need to drop it off to the shop to have the padding and cover put on.I started restoring the right one but it had alot of springs that needed to be replaced then I found a 54 seat that just needed frame repair.The worst you have to fix is you'l need to retie all your springs,thats why I went with the 54 seat it dos'nt have the tied springs it just has little springs that hold it together.
