Jib car screws and nuts definition

Does anyone know the screw and nut size for the two screws/nuts that hold together the jib car to the jib plate to the bullseye fairlead in this jib system:

I tried some 10-24 1 1/4 inch stainless at the hardware store, but they were maybe 1/8 inch shorter than the old hardware; the nut was thicker; and the threads did not come through the nut. I can try the 1/ 1/2 inch, but would like to know if there is a definition, as they cannot be too long or they interfere with the integrated track.

Hobie: can you add a parts blow-up to your catalogue?

Thanks!

Looks like 10/32 x 1 1/2.

These come assembled from our Australian facility, so not 100% confident in the 10-32 part at the moment.
