56 Chevy Pick up 3200 series long bed

[JOHNJOHN]

Hi Folks,

my brother is building a 56 Chevy Pick up 3200 series long bed and he is actually making a complete tubular frame with modern Corvette drivetrains.

I am currently looking for OEM chassis reference for that truck and I'm especially interested to know the OEM front/rear wheel spacing.

What is the distance between front and rear wheels centers ?

Could any of you measure on his/her own truck or provide a link with some information ?

Many thanks in advance
Joan

edit:

Here is a drawing of the 3100 series and I would be happy to find the same for the 3200 series long bed:
