Welcome aboard. You will gain ton of useful info here. One word of caution some on here will be a tad ickish just have a thick skin and don't reply to them.
Having said that on to your question. Boogie is right about BesTop. I am not 100% sure but they may make 2 different kinds of skins as the do their tops. One a little less rugged as the other for those on a budget. I did have one of the Rugged Ridge/Steel Horse flip tops with door skins...Needless to say I went back to Bestop for the replace-a-top but bought a set of slider upper doors (not BT) but they worked fine for a few years. Have since gone with a set of Smittybilt skins. I will say that they work but are not as thick as BT ones however for $50 including shipping from a forum member I won't complain.
No matter what kind you do decide on leave them bad boys in the sun for a minimum of 2 hours. The hotter you get them the easier they will be to get over the metal frames and less chance of tearing the fabric.
Good luck with whatever you choose and Happy Jeepin!
