Topic: The term G.P.D.

[Bossbill]

To make sure I have all of the correct bolts and head marking on my 67 K engine I  started a spreadsheet to figure out which bolts went where. Yes, for every nut and bolt in/on the engine.
I did the bad thing long ago and put all the engine bolts in one box (see other posts on how stupid this was).

A number of things were changed on my engine (water pump, fuel pump)  so I can't be sure of anything, hence the Excel.
The 'concours' fasteners from AMK are all well and good but the head marking are not always correct.

Anyway, while going through the "1967 Osborne Engine Equipment Assy Manual" in order to fill out my spreadsheet I found the term G.P.D. without a glossary explaining what this meant. I believe it has something to do with Police Equipment?

I found two hits after looking at 7 MPCs, one for a water pump pulley and the other for a wire harness.  No definition of the TLA however.  (TLA = Three Letter Acronym)

The Mercury "Y" car is the Meteor.  76 would be a convertible, so that does not make sense for a Police Car.

See page 54 of the 67 ASM where the entire phrase is
 
"INSTALLATION - ALTERNATOR DRIVE R.P.O
55 AND 65 AMP, G.P.D.
55 - 60 AMP L/N
STANDARD & EXTRA COOLING
ENGINE - 289
MODELS -  FORD, FAIRLANE, COMET,
FALCON, RANCHERO & METEOR"

and shows a double alternator belt arrangement on a 289.

Ok, it is an alternator and is described by some 71-73 Mustang folks.
I have a snapshot of how to test one, but that's about all I can find.

...  used for all components released by
Ford's General Products Division (GPD) through model-year
1971. The changeover to Motorcraft - at least for GPD,
which was responsible for Assembly parts - came @ May, 1971.

I think we have a winner. It's a term not used very often in the literature (that I have).

Bill : Nor in my 60 year collection of Ford Literature ; at least as I remember or have looked at lately.

So, 67_1183, what is the source of this information ?

Thanks for finding it.

You mean it's not "Glendale Police Department"?
Jim

[Bossbill]

I was thinking General Parts Depo or Department!

So GPD would be a Ford alternator and L/N is a Leece-Neville alternator.
Interesting belt arrangements . . .

Since it has now been 8 days since I first asked, and still no Reply, I will ask once again :

67_1183, what is the source of the GPD information you provided ?

Thanks,

Bob

I assumed that the picture of the emblem in reply 4 was the providence for the statement.

[jwc66k]

The Ford Car Parts (aka MPC) references in the first, second and third reply seem to imply an option. G.P.D. may be a Police Department special option as one is a water pump reference, the other is a windshield washer reference.
I will go out on a limb here - it is not used on a Mustang.

Bob G : First, I am guessing that you meant "provenance:, not "providence", right ? And no, I don't think that in this day and age, the Posting of an image, especially, and suspiciously, without accompanying text of any sort, can be provenance of the statement. Anyone with even a rudimentary knowledge (like me) of Microsoft Paint, or Photoshop can come up with all kinds of things (see attached).

However, unlike Jim, I do not think it has anything to do with "Police", mainly because police items are covered under the "Model Identification Codes" and "Abbreviations" by either "P.I" (Police Interceptor), or by "P/C" (Police Car).

I do think something similar to the original image Posted (General Parts Division), is probably correct, and even it may be correct, but without documentation, who knows.

I do know that in the Ford Warranty Manuals of the mid-sixties, they refer frequently to the "Parts Depot", and it seems to make more sense in the context in which "GPD" is used.

Still hoping for some documentation.

I verified it's  Ford  "General Parts Division ."

1st pic is from https://aadl.org/N014_0468_001, but posted here just in case it disappears.

"Ypsilanti Ford Addition: Visible at the lower left in this aerial view of the Ford Motor Company's Ypsilanti plant is an 87,000-square-foot addition to the plant, now under construction. The addition will provide warehouse space for the plant, freeing other parts of the plant now being used for warehouse space for additional manufacturing facilities. The plant is part of Ford's General Parts Division and manufactures starters, generators, voltage regulators, ignition coils, shock absorbers, master brake cylinders, heaters, and horns."

2nd (pdf ) is of a LeMans congratulations letter sent to key divisions and personnel.

3rd is a pic of an aircraft alternator that GPD supplied.

After I had some possible options for the full name finding this info was easier.
The LeMans letter is cool.

Bill : Great ! Thanks. Now that's what I meant about having documentation. Now we all know (for sure).

Thanks again for "digging" this up.
