HI All-
I went through the same process, with virtually the same result. The only
real differences are to say that I was also able to run my engine control
cables through the grab bar fixtures, and that I went to the aviation
safety dept of the local Lowes and bought a caulk gun sized tube of
intumescent caulk to seal the works up. I think they called it fire block.
As Bob has previously pointed out, this stuff will swell up and fill all
sorts of gaps when heated sufficiently. It also costs a fraction of what
the re-marketer with the SS cabin heat boxes charges.
FWIW-

Bill and others,
IMHO, I went thru the same thing several years ago. I changed my
heater box for the same reason. I now have stainless steel in place of
the aluminum unit. I went to the aviation section of McMaster Carr and
bought a stainless steel handicap grab bar. It was a short unit but it
worked out very nice, the flange is welded on and I used the 90* end.
This allowed me to get all the wires forward. It is amazing how many
wires go there from the instrumentation we use today. I then used two
fire shield lengths / diameters to close off the opening. I am going to
fill any remaining space with RTV copper hi-temp silicone today. I will
use safety wire to provide the remaining squeeze to seal it wiring to the
fire shield. You can see it on my web site
www.websites.expercraft.com/jimn . That may help you in the decision to
keep the unwanted stuff up front and not on your feet.
