ford gpa g504

Hello to you all
A GPA is a wonderfull vehicle to drive & sail in but what a hell to work on!!
You need four hands and arms of two meters.
Only today I jumped at least 150 times in and out the hull.
Rudder and propeller shaft , brake system, rear axle propeller shaft,
both axles & wheels and several other items are installed.
For the steering connecting rod I'll keep the "African invention" because
this is the perfect system without any leaks or troubles!!
I discovered some very small "F" marks on the clamps of the propeller hose.

Another interesting thing is the bilge pump ajusting valve marked GPA.

Another thing is that I'm curious on what chassis nbr some changes were made.
When did Ford start changing in the production line with the seccond type of instruction plates?
On what ch. nbr. did Ford add. the antenna bracket / reinforcement of the
side coaming?
And at what ch.nbr. did Ford make that big hole in this reinforcement?


Another change is the U- profile at the rear deck.
My gpa (4928) has one U-profile bolted on the deck for the spare wheel carier.
The later types have two U-profiles bolted on the hull.(and a few other changes)
This was done for the extra weight and the extra gas-can , but when did
Ford changed this on the production line?





Can you , GPA owners give your finding and ch.nbr. :idea:

Thanks for the post! I have a question - what are those 3 little brackets for that are to the left of the support bracket in the picture that is number 4 from the top? Are these radio mounts?

Good luck! I'm still looking for some pumps.

Hello Carl

Yes they are radio brackets.
Allso a modification on the later vehicles like the hook on the dash.
Early GPA's didn't have those brackets and microphone-hook on the dash.
Jan Roelse here in Holland driving & sailing gpa for more than 30 years, (Now very busy working on his new shed) has a lot of information of this subject.
Carl do you have more information abouth that GPA in the book amphibious jeeps of Frantisek Koran?
Was it delevered to the Russian forces after W.W. 2?
Do you know its chassis nbr , because in my opinion it is an early gpa
modified to U.S. army standards.
Do you have more information / chassis- / usa nbrs from other Russian
GPA's?
I / we all are interested!!!

In my opinion, due to her original registration number, her frame must be around #3500 (december 1942).

This GPA still have the rear reinforcement for the jerrican, my former #3403 was not fitted with this item so this modification occured after GPA 3403 (december 4 1942).

Her windshield is a late type, My former #3403 was still factory fitted with an early type so this modification also occured after GPA 3403.

It is a great pictures book.

Hello Mithril
I allways want to learn!!, what is the difference between an early
and a late GPA windscreen?

Bob

The difference is just the seal between the dash and the windshield.

On the early ones, the seal is about the same than on a MB/GPW, large rubber one. It is mounted with flat head screws on the windshield.

On the late type, the seal is only a canvas seal slipped into two small metal lips.

I have no room at the moment on my website for some pictures ...

Bob, Late GPA windscreen....
