pcd ??

I may be off here but I think you are looking for the bolt pattern (pcd?). It is 5 bolts on a 5 1/2 circle. There is however another problem. The mounting surface is at two levels, see https://www.fordbarn.com/forum/showth...=1#post1286293

In addition, the wheel carrier is not mounted to the frame, it is body mount. While this might have worked back in the day, there is no way that I would want to hook a trailer up that way today.

I'm with REDMODELT. I have fitted a towbar to one of my As by using the bumper mounts. That worked well but I'd never ever ever try mounting any towing attachment to the spare wheel mount.
Oh, by the way, PCD is "Pitch Circle Diameter". Someone said that the 5 studs are on a 5 1/2" circle. In that case, the PCD is 5 1/2".

Huh? I didn't see Rene say anything about attaching a trailer to the spare tire carrier. Am I missing something here?

Thats because the mordern world is too cheap to spell it out !!!

Dick Steinkamp · 02-17-2018, 09:25 PM

PCD=Pitch Circle Diameter. As Charlie says, for a Model A it's 5 1/2"

SeaSlugs · 02-17-2018, 11:04 PM

At least here in the states there are a ton of cars/trucks that used the 5 on 5 1/2" bolt pattern.

I too say you should make a seperate bar connected directly to the frame to tow with

CarlG · 02-18-2018, 02:57 AM

For a trailer hitch, I bought one of these from Wagner Products. Bolts right on to the rear bumper supports.

pbishop · 04-01-2018, 11:26 PM

That is the way to go.

René W · 02-18-2018, 03:49 AM

Thanks all,i already have a trailer hitch/tow bar attached to the bumper mounts,and i tow a modern trailer with the A.
Now i want to build a matching trailer,i have bought a trailer frame with axle.
This trailer has a brake system i want to use,but the brake drums are 4 bolt pattern so i need to make a spacer from 4 bolt to 5 bolt so i can nuse the model A wheels,thats all.

Nice,but don't need it As i have a complete chassis with brakes i only need to make a spacer plate from 4 to 5 bolt and job is done.I can make this myself on the lathe and mill and only heve to buy 2 steel plates,,,,costs 20 bucks...

CarlG · 02-19-2018, 02:06 PM

I have somewhat the same problem with a trailer I bought. I am going to put Model A wheels & tires on it that match my pickup. Fortunately, the spindles on the trailer will accept Model A hubs, so my plan is to just switch the hubs out. I have already located one hub, just need to get the other one & do the work.

That should be easy then.
By the look of it your trailer has no brakes and that will make it easier to find a hub that fits.
I have already a trailer with no brakes and it is no problem pulling it with the A loaded with 2 veteran motorcycles,tent,camping gear in the trailer,wife 2 dogs and me inside the A..........but stopping is another ballgame.
As i live in a crowded area of Holland sometimes you need good brakes to avoid them idiots in their BMW's and Mercedeses who think they own the road,so that's the reason i want a trailer with brakes,just for safety reasons.
The frame i bought is a former folding camper trailer,can be loaded to 750 kilo and that is enough for me,with that weight there is no need for registration or tax and you can build your own model,model A that is.....

I think everyone is in full agreement trailer brakes deffinately cant hurt. Is it going to be electric brakes or surge brakes?

Which brings up the question; What is the difference between a porcupine and a BMW?

The porcupine has it's pricks on the outside and the BMW has a... well you get the idea.

It is interesting though that BMW drivers are looked upon the same way in Holland.

Surge brakes it will be.
