The Cain triple manifold is pretty tight on the firewall at the passenger's side, but to make matters worse my divorced linkages clashed badly. I can get it to work, but will need to pull off the "swinging curved bar" part of the original accelerator linkage that runs along the firewall (or more to the point, the original triangular bracket that mounts the "swinging curved bar" to the firewall).
I could get cute and put a married linkage on the Cain manifold (and keep the "swinging curved bar"), but after all the drama of making up the divorced linkage, I want to keep it.
Looks like I am going to need to make up a cable conversion. I liked the idea of using the L300 type cable, which has a clevis at one end. The clevis bolts nicely to the section of original accelerator linkage that protrudes from the firewall at floor level. Easy enough to run the cable across, and put a gimble onto my nice new divorced linkage. Trouble is, the original accelerator linkage only has 1/2" of travel. 1/2" of cable travel will not be enough to actuate my divorced linkage... I probably need 1-1.5". The only place I can get that much travel from the original linkage is on the passenger's end of the "curved swinging bar"... which I want to remove.
I figure I need to make up some lever arrangement that lets the cable only travel 1/2", but then multiplies that via a pivot to 1.5". Before I go and reinvent the wheel, has anyone got a working cable conversion (using the original accelerator pedal) that get decent cable travel?
Cheers,
