SWB short bed swap 67 to 70 CST

[briscuba]

I recently bought a doner 67 C10 for my main project: 70 CST 10. Both SWB.

The 67 bed is 95% straight no rust. The bed on the 70 is ugly! I want to swap them. I'm fairly certain it is straight forward bolt up, no?

Also, I want to maintain the marker lights and they were NOT stock in 1967. What's the best way to add rear markers? Cut out from existing bed or cut in new ones?

Thanks for any suggestions.
