[VAC] Water heater cover fix?

[jere potter <potterjrp@xxxxxxxx>]

Friends-  I Could use some help on finding a replacement
part for the cover on my water heater.  My '64 Safari has the original
Bowen water heater cover, which the lower half removes by twisting two
wing nuts at the bottom. I lost the outer part of this cover last summer.
That bit is a perforated aluminum wrap-around, which lets in air for combustion.
It fits into the panel with tabs that are twisted on the inside. I suppose
I could try to fabricate a replacement, but wonder if anybody has an old
one they would be willing to part with, or Ideas for a fix??? Any ideas
would be appreciated!
The scratches on the right side of this tiny photo were
left by the missing piece as it departed my trailer on the move. That was
probably when somebody flashed their lights at me from behind, going through
a mountain tunnel in Glenwood Canyon, CO in the middle of the night. No
way could I stop to investigate.
Brought the Safari down from the Mountain lot last weekend
during a snowstorm- not my choice of conditions, but it was when I could
do it. The day before temps were in the 60's. It made for some white-knuckle
driving, even just doing as little as 5 mph on the steep hill. One touch
to the brakes instantly locked up the trailer wheels in the snow. I wished
I could have thrown an anchor out behind the trailer for more drag. 
4 WD low ratio was the way to go on that part....Thankfully, no incidents
to report.
 I will be prepping "Priscilla" for a week out on
the road to New Mexico, where  I hope to find warmth.
