drag link geometry and Questions

[Blue68]

Guys,
Some time ago, I replaced the front crossmember on my '68 C10 with one from a '75, including the drag link and tie rods. I'm not real sure, but there are a couple of quirky things about the steering that I've been noticing the last two months (finally driving it more). One, when I turn full left/right one of the tires scrubs so hard (like it's gone too far for the radius) it actually slows the truck down. Like when backing out of the drive way, most cars roll, I have to gas my truck. Again, it's only at near full and full lock. Same deal going forward. It also seems to have some slight bump steer. And the drag link/center link actually rubs against the crossmember. The link is level, so I think my pitman arm and idler/follower arm are fine (used to be a manual steer truck, now has power and is lowered as well).

Could someone measure a stock '68 Chevy center link for me?

I'm pretty sure the drag link is off the '75 since the inner tie rods are stock '75 pieces (no adapter sleeves). But I'm thinking the pitman arm and idler arm are '68 pieces. Maybe that's why there's scrubbing?

Any front end geometry wizards out there that could provide guidance?
