Tom he bought a sleeve hitch and didn't get the pivots for the trans.
Animal to answer your question they are 4" long and have 1/2"x13 nuts with 1/2" x 1 1/2" bolts,
the pin sticks out 1 1/2". Like Bart said get some 1.25" x 3/16" tube.
If it were me while I was making them I'd make a few sets.
Your not the only one that didn't get them or that they got them but they were bunged up.
If you can sell them they would probably pay for your hitch.
Take pictures and do a write up while your at it.
Before you ask those aren't extra one I have they're off my hitch. :thumbsup:
