I don't have one to let go ( cause I really love mine),,,,,, but remember someone was able to get just the mounting plate. Then they attached another type/brand of bag to that and it worked out well for them.
I'm not real good with the searching ,,,,,,,,, but I'll see what I can come up with.
Ok,,,,,, found the thread, but it doesn't look like the plate is available, or I'm not seeing it :?But it might be worth giving them a call.
I know this is an old thread.... but I am on the hunt for a Firecreek Tank Bag. I found a rack, but I would like the actual bag. So if anyone has the actual tank bag and is not using it.... PM me and "lets make a deal."
I saw Dusty's rack and bag last year at the Misquote Round Up and for me it is a must have.
