CMC Rules - Ballast, Fire, Battery and Accusump placement

[Fbody383]

I was thinking to use Riv-nuts in the floor to secure things. I've found them to be very solid when installed correctly but has anyone had issues with riv-nuts coming lose on impact?

If you were talking about a threaded fastener in 1/4" material I might be able to agree, but not the sheet metal on these cars. I would not personally use a riv-nut to mount anything substantial - I did use them to mount the brake prop valve. For the battery, I ran a strap of 0.90" from bolt to bolt, so a giant "washer."

You don't want that stuff coming loose.

I'll take your advice and thru bolt it for sure...Thanks for the feedback

Anything that goes through the floor should have fender washers ideally. They also make heavy duty fender washers, I found those at Fastenal. I like using those for ballast.
