Air Grabber Vacuum Canister

Can someone tell me what type of fastener Mopar used to mount the Air Grabber vacuum canister to the inner fender on a 71 RR ? I can't seem to find any information regarding what style,type,length & etc was used. If someone has a pic of what was used, that would be super fantastic. Thanks for any information that can be provided.

It's a raised strap crimped to the can.

Thanks for the response and pic, but I should have been more precise in my question. What I need to find out is what type of screw or bolt and what size was used to mount the canister to the fender ? The supplied pic appears to indicate a black phosphate bolt or phillips screw of some kind ? I can't make it out good enough to tell.

Hex head Black Phosphate self cutting type, don't know the size. You can check with Frank Badalson or RT Specialties
