Welcome! First off, what year is your car, how many miles, etc? What shifter do you have?
For reference, I have an '03 bugeye with 95k and a Cobb short throw shifter myself, and I've never had this problem, but 5th gear is pushing the shifter linkage very close to the metal boot plate. Take off the shift know and center console trim, then run through the gears with the car off. Do you see any contact between the linkage and metal ring?
