There will be an additional charge of around I think $100 for welding the slot closed, Plus the charge for cutting the dovetail on the front. Of course the rear will need to be cut too. Novak's does excellent work and usually has a quick turnaround. I highly recommend them as I have had a lot of work done by them.sounds like sending it out to novak for dovetail cuts would be easier. Thank you for the knowledge, I appreciate it
