WOW ... you have got to do alot of comparing. Input shaft lengths, spline diffs, pilot bushing ID's ....etc.

like Doc said, you'll have to do some measuring. I'm sure that Advance adaptors has something that you will help you adapt an OD manual to your LA 318.

I would look at putting on a set of taller tires or maybe a spread-bore carb ...aka a ThermoQuad.
