65 C20 to C10 changeover

[Captainfab]

I do not know if the C20 LCA shaft will fit a C10 LCA. I've never tried it......no reason to. Yes the crossmember is different as I stated before. There are no saddles to accept a round LCA shaft. I have a pic of a '63-'66 C20 LCA but it is apparently on my other computer.

Finding pics for this stuff has been tough, so any info you guys have on the c10/c20 differences will help a lot!

Here's something I was just wondering, is the actual crossmember different between c10/c20?
