bed mounting questions / opinions

[mikec4193]

Hi Everybody 47 to 59 Chevy truck

I have been mounting my pickup box to my 1952/53 Chevy truck....I bought all the parts...found detailed instructions on line as to how they bolt everything up and I am still wondering to myself...

Whats up with wood blocks that holds all that wood and the bed sides too thing up off the frame rails???

And the sliding slotted pieces that go under the channeled crossmembers???

I have never seen this much wood used in a vintage vehicle before....is this really the way they all went together back in the day???

I am trying to keep it as stock as I can so when sale day comes there will be less questions asked...would it not have been safer/smarter to use square steel tube to mount all this stuff too frame rails???

Just wondering out loud thats all....
