Cab fuel tank bracket removal?

[tigerburns]

There are 2 brackets located on the floor at the rear of the cab that hold the gas tank. For the guys that have relocated their gas tanks out of the cab, have you removed these brackets or left them in place?

I have relocated my tank and want to add sound proofing to the floor and up the back of the cab. What have you guys done with these brackets in a similar situation?

Thanks for your input.
