Yes, you could shave a 1/2" off. However, you will lose a very nice detail [ rounded end ] on the stainless steel trim and the embossed word, "Chevrolet" would not be centered on the trim...it would look kind of funky.

I would need to see a photo of your dash...maybe it will work for you.

When I go cruisin' in the old truck....women smile, men weep and dogs beg for rides.
