I bought some dual weber carbs for my 1972 240z and I just finished removing the stock SU's and noticed the coolant passage won't be blocked by the J manifolds provided. Basically the manifolds on my car are square and on the bottom have a passage for coolant, but the new cannon manifolds I got are perfect squares with no holes for coolant which would'nt block the coolant holes. The person I purchased the carbs from told me it was a direct bolt on and I don't think that's possible unless you're supposed to block the coolant or reroute it? Can someone explain to me how to install these correctly? Nevermind, I blocked off the coolant like I mentioned and it seemed to work well. The first picture show's where I plugged the lines and the second one is after everything was finished.

I recently purchased a used set of weber carbs online and the only thing it's missing are the gaskets between the carbs and intake. The cannon 2830's (I think that's what they're called) are just in need of the gaskets. My question is does anybody know where I can buy these gaskets?

Thanks Matt K/dexter72. You both just helped me out a lot and I really appreciate it!

I'm a newbie and couldn't find it. Mind pointing me in the right direction? And sorry if this was sort of a stupid post..

Hey everyone, I have a 1972 240z and I'm thinking about swapping out the L24 with a 1979 L28e engine. I've read that the engine mounts are identical and that the 5-speed trans will also mount right up but I haven't seen anybody mention anything about the fuel lines. It concerns me because the L24 has the dual carbs and the L28e is fuel injected. Also will the engine harness connect to the older body harness? Or will I need a new body harness? Any info would be greatly appreciated.
