Outer Limits 4x4 Board

Hey guys, just did a search on this but still have a few questions regarding the seals. I've just fitted some second hand fibreglass panels (the ute cab version) to my 89 soft top. Got one or two leaks and fitment issues but I expected that! Now I can probably find and replace the four main seals in the roof panel (although they dont look too bad) but has anyone ever tracked down the four molded corner rubbers that interlink with the main seals? The ones i have are pretty secondhand looking! If worst comes to worst, out comes the silicone and the roof never comes off! Sorry to drag up an old topic but I figured it couldn't hurt to ask.
Cheers!
