I just got a 76mm C&L MAF from a guy off here, and it has a 30# sample tube in it already. I need a 24# sample tube for my setup. I know somebody on here has to have a 24# sample tube they arent using/want to sell. I know this is the wrong forum, but I've already posted it twice in the "Classifieds" w/no responses. I called C&L about doing a swap, and they said they'd probably do it, but werent thrilled about it. Especially since I didnt live near by so they could check it out/test it before they sent me another one. And a new one is almost $40 shipped. I know somebody on heres got one they dont need. I be willing to buy or trade my 30# for a 24#. Help me out here!!! Thanks in advance.
