Thanks for the tip. I Have the metal 372 clamp on the way.

Dan Henry told me about the 372 clamp. 

yep,that's a good mod. of course HVA has had the same pic in one of their service bulletins for some time.

If you look at link how to trim old plastic intake clamp to be able to use the new metal clamps.   

Doing one yesterday I wondered. What if you trimmed all the plastic intake clamp part away to just use the 372 clamp straight to the rubber boot part. 

Am I missing anything to way this cant be done?  I dont see where anything would be pulled apart from use. So what am I missing in this thought?

The last 372 clamps I ordered was updated to a new one too.  Cant remember numbers.
