The black frame came with the trunk. It's fairly light gauge so I don't know how well it will last, but for the price I'm willing to see. They sent a luggage rack with it to but the chrome is so poor I didn't want to put it on.
I have no doubt it COULD be adapted to a Savage, but it's may be too big to look right.
There are a lot of cheap trunks on Amazon now.Some would look better size-wize on the Savage than this one.
