My CUCV plow is a Fisher Speedcaster, but I believe I know the pins you speak of...Thanks for the reply. I am not sure how to post pics.
The pins I am referring to are the 2 pins that attach the plow assembly to the plow frame on the truck (at the end of the A frame). I am running an old Meyers plow.
I have tried all kinds of pins, actual Myers pins, hitch pins from the farm supply store, and pins for reciever hitches, plus a variety is spring clips on the pins, but still manage to lose them quite often. There probably isn't a better option, but I figured I would ask.
I was able to heat up the hinge bar and straighten it out enough to get it back on the truck last night, but the metal is stretched and probably won't last long. Hopefully long enough to finish my parking lot and driveway.
I have ordered a replacement hinge bar and will cut the old one off and weld the new one on when it arrives.
Looking here: https://www.fisherplows.com/parts-service/parts-list/poster/mc-series-a-frame-components/
...near where the number 178 is seen, there are three holes on each side of the A-Frame. You want the spring-loaded pins that go in there, correct?
Since yours is a Meyer, let's take a peek there...
...possibly parts 17 and 18 in that diagram?
