I have this unknown toyota forklift. Spec plate says FG20 and serial number is BET85002 and the same serial number is stamped on the right side of frame. It looks like it is a 1970-1980s forklift. It has 2 shift tension/ trans belt adjustment bolts on top of valve body on trans. I was told they were shift tension bolts. I need a replacement bolt since the original is missing and some one just put a bolt in its place it has a slot screw driver on top and has a spring as well. I cant get the part because no one can identify this dam mystery lift.
