Is anyone making the correct 1/4-28 engine dust pan bolts. These were used on the brass radiator cars.

No.
The heads are 3/8" square. Different years' parts books list different lengths.

I know of three different lengths. The front ones are 1/2" longer on the cars. Then there was an even longer one for the rear on the deeper frames of the TT's. All have a smaller head than a standard hardware shop bolt of today. A few I have seen do not have the four pointed square under the head. Instead, they have just two points. All have used a larger square nut than those found on later general hardware. Now square nuts are made of unobtaineum.

Allan from down under.

One thing has hasn't been mentioned is the little bolts have a cotter pin hole through the bottom.

From the 1912 catalog:
1/4" x 9/16" quantity: 7
Here are some that I believe Richard Eagle made:
