5th wheel plate...67 c10

[longbed67]

Hi I am flying out to washington state to pick up my new baby in 2 weeks, it is a 1967 c10 long bed 250 I6 three on the tree... I will be driving her the 2200 miles back home and starting a frame off restoration. I am currently ordering parts now so that they will be here when I get back so I can start laying things out, my question is though, does any one know of someone who makes a 5th wheel plate for this truck I am looking for one that I can flip the ball and just have a hole in the wood floor and not something I have to bolt on top. I havent been able to find one, I would rather purchase one than fab one but if I have to i will. Thanks in advance.
