However, they have to import these items, since its from a company over-seas. Even though you said you didnt want to take off the old trim, the E&G stainless door trim is real nice too. The trim comes off easily enough (I wedged an old credit card behind it and worked my way around!!) The E&G trim is also cheaper in cost. Any way you choose to go, its a subtle, but nice touch.
Keep on Cruisin!
