Yep, 342 fits (relatively) perfectly. You just need to trim the bottom part of the housing…make a little cut out.And of course I find my answer right after I post. Oh well it appears to be the 342
But when you do that, you also have to eliminate the fuel pump bottom, rubber cushion! I bet you it would be real loud and the vibration would "buzz" the $h!t out of that trimmed lower cap... Lotus makes a larger lower cap for the Cup260 cars that allows the use of that lower rubber cushion and makes the installation all right.Yep, 342 fits (relatively) perfectly.

They are also common in 90's Honda applications, so you can find them pretty cheap. You do not need to go to a Lotus specific parts place. I found one locally for $85 new from an import tuning shop.
