I did call wilton and the gentleman I talked to was very knowledgeable on the newer ones but not as much on the older ones.
He also was thinking since it was the same casting number it should work.
I have a 4 inch wilton vise with a broken dynamic jaw. The casting number is 101027 dated 6/69.
My question is will a newer 101027 jaw work? Only difference I see is the length of the key.
Mine the key way is machined out farther and the key is longer. The newer one is shorter.
Thanks for any...
