I know most RHD 131 owners perfer DCOEs because you don't have to deal with the master cylinder. We lefthanders have to use IDFs.
I mounted my IDFs on my Brava and the intake manifold fits perfect compared to when it was mounted on my 81 Spider but the location where the throttle enters the engine compartment is putting the cabel in a bind. Plus the kickdown cable is touching the carburetor. But that may not be an issue.

As of right now the only thing I can think of is installing some longer studs and raise the throttle mechanism up about 2 to 3" to clear the carburetor and hopefully the air cleaner. But it still seems like the cable is still going to be in a bind.
Any suggestions?
