Thanks Dick, excellent point. I have a full bag of ss rivets from MAM and the moose instructions have no reference to the firewall at all. So I will use these and look over the regs.
Thanks

You fellows in Canada might want to try:
Rivets Unlimited (Toronto) Inc (905) 612-9220 2696 Slough Street
Mississauga, ON L4T 1G3
In the USA I got all of my unique hardware (big bolts half sized rivets etc)
from:
GENUINE A/C Parts, Paso Robles CA, 805-239-3169, 800-247-2738
www.gen-aircraft-hardware.com
I used hard, driven, SS rivets for most of my f/w work. MS20615-4M4,
MS20615-4M5
The Firewall needs to be able to hold up to 2,000*F for 5 min per the regs.
Not a place for short cuts!

Thanks Ken, I think your right on the fire melting the aluminum ect. I'm
just not sure about the reaction of aluminum, stainless and galvanized.

I'd vote for stainless. A fire barrier is only as strong as the weakest link
and aluminum will melt in seconds in a fuel fed fire. Some guys have said
the stainless pop rivets don't always retain the mandrel which could leave
them hollow but mine were OK. That said I did use some avex in non critical
places although perhaps should not have. But the entire firewall is fastened
to aluminum so there are limits to the advantages of a stainless rivet. BE61
stainless structural rivets could be used if someone is really picky. Ken
