How many attachment points in a 1940 Ford Tudor

[Canuk40]

I am working toward removing the body from the frame and have been looking for bolts holding the body to the frame. Since I have already removed the entire floor, the only points I cannot be sure of are those starting at the rear seat kick up working rearward to the trunk.
How many should I be looking for, and where exactly are they located?

check rear edge of floor in trunk, towards the outside corners and outer edge of firewall under the hood. That's where I found 4 in my '41. Probably '40 is pretty close.

Never done this on a sedan, but pretty sure the rear mounting points (four) are the same as on a coupe. Should be one on each side just behind the rear spring crossmember (on frame top) and one on each side of the rear frame crossmember (a few inches inside of the side frame rail).

Edit: Here's a picture from Bob Drake catalogue.

If you are putting in new floors in the car you should leave the body on the frame. Taking it off the frame and installing the floors may cause a lot of misalignment of the doors, etc.

Randy - You are the man. I looked at Drake's site and couldn't find it. Thanks.
TJ - I am doing as you suggest. I have the reinforcement of the B pillars mostly figured out. Very busy place - floor, rocker, rocker extension, B pillar and rear fender tab all come together and attach with 1 bolt. Won't tack it together until I test fit the doors.
As for A pillar, I am replacing both left and right cowl sections with parts from Dennis Carpenter. Promises to be an education in fabrication and fitment.
Once I have all put together and doors back on for fitting, I will detach the completed body and swap frames.
Any additional input of suggestions always welcome.

Sounds like you have a good plan. You've taken on a project that many would not do and saving an old Ford.

Work progresses on the rust repair. Have fit the new floor and am working on attachments points to frame.
Bought a bolt kit from Drake's (bolts, nuts, washers).
In the kit are 3 lengths of hex head bolts, which should be easy to place.
Also included are 14 bolts (I think they are called Class Bolts). Round heads and squared at top of shank below bolt head. Typically they need a square hole to lock them in place so a nut can be tightened.
No idea where they are used. I sent a message to Drake's but received no reply, so am hoping someone here has an idea where they are used.

Drake used to have the illustrations in their paper catalog.

I'm doing much the same as you on a '51. The bolts you are describing sound like carriage bolts. My car is not a restoration so I'm using regular bolts that are capable of the task....Mark

They are probably the bolts that fix the running boards to the frame.

The bolt head fits into the frame with the thread facing out and the running board has washers and nuts to secure it.

Didn't think of the running boards. Sounds promising. Thanks for the info.

Carriage Bolts?

 

[Canuk40]

Yes, they are carriage colts,( I originally misnamed them - They are also called C Class bolts.)

I looked at the running boards and frame mount locations which are square - so 47Merc is correct.

Thanks all for your input. Now, on the the next thing.
