Thanks I will email you my contact as I was concerned about being able to get part and any help and advice from people in the know is very welcome

 

It's a F5, the F6 had 8.25x20 tires and the frame on the F4 was not double.
Hate to see u change the running gear as Old Henry built a good drivetrain for these trucks. We had a fleet of F6 dump trucks in the grading business and u could not kill them. Is yours a 6 or 8 cylinder?

 

Very nice looking project. I think mtflat is right about that front fender light. It does look like a '48-'50 mercury fender light. Can we get a better look at it please?

Yes it is a v8RT unfortunately locked up we will try and free it up but from what i was told it may have done a head gasket dare say thats why it was parked up and got water in the bore.Not to say I won't keep the drive train and rebuild it over time so i will alway have that option. Greg I added the only pic i got of the front till I go back to the yard Monday I gather these are not the factory lights?

Thanks for the help IDing guys I think I can safely say I have a F5 I will post up the numbers if we find any under the cab. Still a bit unshore of the year but we'll work on that

 

No, I'm not saying that those lights aren't factory correct. I'm saying that they look like the lights that Ford of Canada put onto Mercury trucks. And from the picture they do look like them.
Could be something they did for the Australian market? Just neat to see them put to another use. I'd be interested to see how they were mounted. Those lights and the way they were mounted caught a lot of dirt and moisture which ruined a lot of these fenders on the mercury trucks. Then add the stainless and there mounting holes. A lot of dirt traps.

We've seen that park lamp set up before on Australian trucks. Someone posted pics of Aussie 48-50 trucks before and it was noted then that the traditional upper grille bar park lamps normally seen on North American models are replaced by the fender mount units. It's a "down under" thing. I'm guessing the Aussie government wanted marker lights closer to the outside edges of the truck, and not set so far inboard.

I'm going out on a limb and saying the stamped number you found on the frame rail, 9G12878, is your vin. It's consistent with the location, style and type seen in up North. The 7R8T number I believe is a part number for that particular piece of the frame. The vin is unlike the sequence used in Canada, but more like a partial vin used in US production. But the G is not a code I'm familiar with, and the smaller size is definitely unique. Very cool truck.

 

There is this photo in the working trucks thread that shows Mercurys with that turn signal light https://www.ford-trucks.com/forums/9...l#post10098508

 

Hey blue cloud. Those lights are just running lights. The first click out on the light switch turns them on. One more click to the full out position turns the main headlights on and these turn off.
Not really sure why you would run with just those small fender lights on ?
Might convert mine to signal lights some day.

Yeah, who needed turn signals in the 50's ?

 

My F3 had those fender lights also, the idea was if you had to park your truck at night and walk away then you'd leave them turned on to prevent someone hitting it, very small current draw. Same theory as cowl lights on vintage cars.

 

Great photos of the numbers on the frame parts. They are really clear. I will have to look close on my truck to see if I can find and record any identification numbers. There are many knowledgeable people on this site to help with these identification issues.
