School me on 4-spd pedal interchange

Don't really know if early a and later a's can interchange.

Almost certain that they don't, at least not without a bunch of work.

Pretty sure that the early pedals actually surround the column, clutch pedal around the left side and the brake around the right. The later pedals are both on one side of the column. The wrong pedals interfere with the column and require lots of cutting and bending to fit.
