Thanks Chuck. I imagine it will come to something like that, and experience shows JB Weld can handle it and more (the super-duct tape of fixative goops), so, 'good idea', though I'm a little leery of making a mess with the stuff.
How were those pieces joined in the first place?
And tangentially, did yours emit a nasty buzzing at certain engine speeds? [Something on mine now does just that, and I'd been telling myself that I had things pretty well sorted. In fact, looking for the source of the racket led me to the loose grill bars. I've found no other likely sources for the din, was just wondering if anyone else's experience with a similar failure also resulted in an unpleasant rattle-buzz.]
Cheers all,
Denny
