They are a sheet metal or wood screw type.......Pointy at the end...I measured one; Thread diameter is 6.25 mm and 1.75 mm between threads. Head wrench size is 10 mm and thread length is 1 inch (25.4 mm)





The head is kind of odd- It has indentions in the top...All of the body attachment screws are the same......If you are short a few, take a couple from the front fenders and put them in the rear....later, when you are at the local JY, grab a couple of spares from a scrapped Fiero.
