69 Swinger 340 project

I picked up a 69 Swinger 340 in October. It's my first project car in 12 years. The last one was a 71 Road Runner. This is my first A Body. When I got it home, I dove right in and found the complete broadcast sheet behind the rear seat back. Turns out to be an all original car with 75,000 miles. Been sitting for 22 years before I bought it. It came with the #'s matching 340 and 727 A/T. I've been tracking down the only mising items, AM Radio, Bumper jack, and unsilenced air cleaner. Had to settle for the chrome Mopar Performance unsilenced air cleaner. Has anyone had any luck stripping the chrome and painting the air cleaner with the black crinkle paint? If so how did you do it and how well did it come out? Thanks
