Hi looking for help please just purchased a 3.4 auto and the steering cowl and horn ring are removed the parts are there, but no screws, can any one tell me what screws size are needed to refit?

 

I think they're 10/32.
The ones that hold on the Bakelite cover from underneath may be 12/32 panhead. (there's three of those)
The 3 that hold the horn ring in place are 10/32 cheese head as well as the ones at the back of the steering wheel, only they are quite long, with out measuring, about 1-1/2 inches.

I'm typing this all from memory.
