I was thinking it maybe nice to keep a sticky with all the wierd bolts listed.
To start, the pintle is 1 1/4-12.
I had to run a tap thru the castle nut and also ran a die down the pintle itself, turns so much easier now.
p.s. the machinists at work really enjoyed me telling them some of the threads were fubar'd due to me beating the heck outta the thing with a big sledge to get it to come loose....
