For Those Doing Disk Brakes. 60-66

Yes your '63 C10 will have the saddles to accept the '73-'87 LCA's. I would recommend drilling out the LCA U-bolt holes in the crossmember and upgrading to the larger diameter '73-'87 U-bolts when you reassemble.

I really don't what to change the x-m out or have to modify a bunch of stuff to make it fit. anyway thanks for the input.
