Hey guys,, i'm using Arthur Pirkle's book to get thread & screw sizes ,, there are "3" screws on a 76 that require a 3/16 x 36 screws,, the side plates are 1 of the three. But a #10 X 36 is the same. Looked at Homestead the tap is $ 22.00 + shipping ,, the die is about $9.00 + shipping ,, can order from d-bay for about $ 5-8.00 for both ,,,, IF you don't mind waiting ,, & waiting & waiting , to come from a place far-far -far away. ( Will probable do Homestead ).
Dusty o'l son hope everything their OK, glad to see you on here.
( bad day ) need coffee,, Hootmix.
