Hot Rods Vintage Salvage Yards on I70 Corridor from GA to CO?

Brad54 is heading to Colorado from Georgia along the I 70 corridor (through Tennessee, Missouri, Kansas, etc) to pick up a transfer case and PTO for his '61 K10 project and is looking for any good vintage salvage yards to stop at along the way home.

I know about John's Auto Salvage in Cabool, MO and passed the address on to him but any names and info are greatly appreciated!

Thanks, Bill
