Dear Nelson,
As someone already suggested, the exact value is not critical. In any
event, you can always trim any resistor to any value your ohmmeter or
bridge is capable of by simply buying gobs of Radio Shack resistors in
various sizes and put them into series parallel combinations to get any
value you want.

The important thing is to get them well sealed against the WX.

It won't do any good to fuse them agains lightning, because it will
just jump the fuse holder. Plan on losing them due to lightning and
make an occasional check with an ohmmeter to see that all is still OK.
