I have some Olds 455 wet logs, hoses and tips. They are Guardian I believe. No cracks, pulled em off when I put on OT Twisties.

they're yours for 100 bucks. Located in Livermore, CA. (just realized where you are at, I can ship them too for the added shipping cost on top of the 100, dunno what that would be offhand)
