Body bolt diameter?

[JayJay]

All - I'm building a rolling dolly to mount my Town Sedan body on after I remove it from the frame. I plan to use the existing body bolt holes to fasten the body to the dolly, but what is the diameter of the body bolts? I don't have the car handy to me to take a look. I realize I'll need to remove the carriage bolts that currently fasten the wood main rails to the frame and install standard threaded hex-head bolts to fasten to the dolly, but what diameter? My recollection is that they're probably around 5/16" or 3/8" diameter. I looked in the catalogs and I don't find a diameter, just a pre-assembled body bolt set.

Thanks in advance.

7/16 is the frame hole size.
now im unsure but at least 3/8"

using UGLY`s drawing, #`s 12&3 are 3/8 the rest of the bolts to the frame are 7/16

Excellent, this is just what I was looking for.

#1 I think is the hood stop, and #s 2&3 are the hood latches (aren't there also some pads for hood latches not shown towards the front?). The rest are the bolts that go from body to frame. Looks like 7/16" is the winner. I think I'll tap my dolly for 3/8" and use those to bolt the body to the dolly, that gives a bit of wiggle room within the holes.

Thanks again, folks.

#1 is at the front of the cowl and #2 & #3 are at the rear of the cowl. Is the diagram posted correct for your Sedan?

[old ugly]

the diagram came from Les Andrews red book.
if you want specific then the book shows all the models and the related mountings. i just pick one as these bolts will be the same.

For just bolting the body to the dolly, does the hole size really matter, As long as they're big enough?

Katy, you're correct, no it really doesn't matter. What I wanted to make sure was that I didn't plan to use bolts that were larger than the holes in the wood rails as I'm hoping to save the wood rails. As I mentioned, I'm going to use 3/8" all-thread upwards from the dolly through the body wood rails. I have cross members on the dolly at positions 4, 5, 7, 8 and 9 (on the diagram supplied by old ugly), and will likely bolt every other one.
