I need of some information. I purchased a bunch of integral hitch parts that included everything except the actual hitch. I am putting it on my sub 15000 1964 110. The pin I received for the pulley s round head drilled pin that is 1-5/8 in in useful length. When I put the pin in to the bracket it hits the neutral switch bracket without going all of the way in. I have the original instructions for the install and the parts list says that the pin length is 1-5/8 in. but the instructions says the pin is 1-1/16 in. I am certain that the shorter pin would fit, but the parts list never mentions this was an alternative for the sub 15000 units. Anyone know whether the shorter pin is what should be used? I can't cut the longer pin to the correct length because it would open up the cotter pin hole. Thanks in advance.
