Did all ca's have a constant-mesh transmission or were the early one's a sliding gear, like the wd? Ron

Thanks. The parts book shows the gears were changed in early 1952, I was just curious what the change was for?

Maybe to strengthen some of the tranny parts.....

Now I'm curious as to what was changed, and if parts swap between all CA's.
