Can anyone tell me if I can use the stock tank after installing the USTOOL leaf relocation kit in a 67 Belvedere?

Don't know about that particular kit, but I moved mine in as far as I could and still used a stock tank. Had to roll the seam up with a deadblow,but it fit. You will not be able to run tailpipes between the springs& tank afterward.

Thanks, the USTool kit puts the leafs right on the frame rails. I'm okay with the exhaust but would rather keep stock tank and location.

I did my sons RR 20 years ago with the MP kit, but I welded the stock front hangars inside for additional strength. Used the stock tank, but had to run the tailpipes beside the tank to fit. Only took an afternoon, and did install abody SS springs too. Finally put back to stock location last summer for older son who inherited the car after younger passed away. It looked pretty cool with 12" wide mickeys on cragers tucked under it.
