Thanks guys
I've looked at a couple of you tube videos and they aren't much help, at least for me.
Joined the huntfishnw group to check out the thread Alk linked to, but, though it looks pretty good from the description, for some reason I can't see the pictures.
Will mull the do-it-yourself over until next weekend when it's supposed to be dry outside.
But you got to remember, as a mechanic I'm a PLO guy (PLO = parts left over).
