Did Chevy change the setup/rigging of the emergency brake system between the years 1947 and 1952 on their 3100 series of 1/2 tons?

I have a 3100, '52 1/2ton and need the whole set up from the foot stomper to the brake release. I might be able get parts off a 47/48 truck if they're the same. I have one schematic of the e-brake system, but it's a drawing and hard to see what it really looks like.

The '52 has drum brakes in the back.

Thanks in advance.
