As some of you have read I am getting a new to me Silver Sabre uMax. I bought it off a fella on eBay, I see by the pictures that bolt that holds the coil to the lower rod is metal instead of plastic. My thought is that it should work ok as long as it is tight enough so it doesn't move. Or do you think it would be wise for me to drill out the coil holes and lower rod hole so I can use a plastic bolt and plastic nut. Thanks! Steve.
