OK folks let me put in two cents worth.
1. You can chrome fins.
2. I will never do it again.
3. The chrome does not go down between the fins, that is why I taped mine off and painted down inside.
4. The bushings can be removed and replaced, they cost $70.00 per side.
5. All in all they look good but are a pain in the ####
And just to add this note, the chrome shop that does all our chroming, told me never to bring in any more. They had a real hard time because of the process and bubbling of the chrome before they finally got them completed.
Polishing and diamond cutting would be the best bet.
enjoy the ride
