ford gpa g504

Hi everyone
I am not sure how the floor plates are held in place,My first GPA had mainly 5/16 in pan screws.I have seen most gpas have 5/16 in hex bolts.What do you think is correct? :roll:
Thanks for any help Rick

Hex bolds (5/16) ...

Rick,

In most instances where foot or hand contact can occur (as in the floor boards or deck plates) the specs call for "Binding Head Screw" which is similar to a pan head but different. While there may be some locations that hex head bolts are used (like beneath the seats) the majority are binding head screw. See page 76 of the Parts Manual.

For the most part, this is what I observed on my late model GPA. I do not know if earlier models were different.

Good luck,

Donovan.

Thankyou for the info.I will now use the required number of binding head screws as indicated in parts book,
thanks again

Rick
As Mithrill told you allready the GPA floor plates are fastened with hex bolts.
The floor plate with 5/16 and the smaller plate round the gear shift
1/4 bolts.
The "pan head" bolts are used for the upper deck plates.
The big ones (pan heads) are used for the head lamp brackets,
the small grills beside the fuel tank.
Two small ones like the deck plates are used to fasten the inspection hatch between the two front seats.
Here a picture of the untouched GPA 4926 of the South African Museum.


Greetings Bob

Bob,

Can you explain why the parts book says binding head screws? While my floorboards were not in place when I received my GPA, I see more binding head screws than hex bolts. This may be a early versus late thing as my GPA is a late version.

Hi, I think everyone is right, The difference is in early and late production from what I have learnt.My late modle gpa which only has 4000miles or so has not been tampered with and it has mainly 5/16 in binding screws in the front floor and 1/4 binding screws around the gear shift,It was like that when I got it.One of my early gpas had only hex bolts, but I thought this was incorrect,Thanks Bob for showing the images of the earlyuntouched .gpa
Thankyou everybody Rick

Hello Donovan, Rick & others

What is original or not?
With my GPA it is easy because mine is 4928 and the one in the
South African museum is 4926 and untouched with only 184 miles on total and day trip counter!
So for me there is no better example than that GPA!
It is posible that the hex bolts are changed into pan head screw bolts on the later types but I' ve never seen this.
I don't trust a book (TM) I only trust what I see on pictures or on the vehicle itself.
There are often mistakes made in the original TM's.
For example like the Jeep TM 9-1803A installing connecting rods and piston assemblies page 47;
"....oil squirt hole to the right hand side of the engine" and further on;
"....oil squirt hole to the left hand side of the engine".
The 12 MWO's were dated but the actual practice was much later!
Here a picture of the pan head screw bolts on the headlamp brackets and the
3 normal hex bolts on the B.O. driving lamp bracket.
