I would like to know if the screw asm that holds the B/B fan shroud to the fan shroud bracket onto the rad support is the same one used on the small blocks. The assembly manual only shows the insulation of the small block rad and fan shroud. The screw asm in they show in asm manual is 1/4-14 x 5/8 3/8 AF with a 3/4" washer. The car I have has a 6A build date if this makes any diference ?
