What year are these

Hello to all. Its been a while since i've been on here but got a puzzle for the Dodgy gurus.

I'm looking for either of these for a build but cant figure the year of the white cab. The yellow one i can see is more common than the white

Note the White looks to have had a body chop below the belt line.

Thanks in advance Mick

38,39 and 40 was the years for that style I believe

Yes from what i can work out 38 to late 40's for that cab style but the bottom of the door on the white one swoops down below the guard. Could it be 38 only

Looking at it the white one has been channelled.

I actually prefer it and I'm not a fan of chopped vehicles.

One of those in Australia would be very rare.

Really subtle chop to the point that if you didnt know these trucks you wouldnt realize it had been done. I think it has made it proportional to its low stance.

Very clean lines on it too with the custom tub. Its my inspiration for a future build
