 Is there any galvanic action to worry about when using galvanized
u-bolts with an aluminum boom?

  I know stainless can touch aluminum directly but Dick's note made me
wonder about galvanized steel and aluminum being in contact (have a
couple here and wonder if I should replace them with stainless)...

Thanks to all who responded on this. A lot of searching on the web leads
to conclude that stainless u-bolt sizes do not come in 1/8" width
increments, only 1/4" increments. However, I have found some zinc-plated
u-bolts that do come in 1/8" increments. This makes sense because
originally supplied plated u-bolts for the 40-2CD. For reasons I won't
into, plated bolts would be OK in this case (not to mention a lot
Unfortunately, my web search has not turned up a supplier who has the
sizes I need. I'll keep looking, but if anyone can point me in the right
direction, here are the specs:
   Inside Width         Length           Thread
     2 1/2"             3 1/2"            3/8"
     2 1/8"             2 3/4"            5/16"
     2"                 2 3/4"            5/16"
     1 5/8"             2 3/4"            5/16" 
The lengths are not critical -- a few eighths one way or the other won't
a problem.
