McMaster-Carr has a great selection of U-Bolts but I doubt that you
will find one that is 1/4 diameter with a 3" C-C. %/16 would be a
better bolt choice if it could be made to fit the clamp.

Greetings,
Last summer someone in the club decided tighter is
better and mangled the threads on the U-Bolt that is part of the mast
clamp on the club's Alliance HD-73 rotator. It is Alliance part number
X-19434-B.
An email to Norm's got a message back saying they will only sell the
whole clamp assembly.
A trip to several hardware stores has not turned up anything that fits.
I am not a machinist, but my measurements say the holes it goes
through are at most ¼ inch in diameter. They are 3 inches apart center
to center.
I would love to find something the same original shape, but I think a
standard U-Bolt shape should work.
Anyone know where to get something that works?
Thanks and 73,
Gary "Joe" kk0sd
