These 1958 Belair inside window cranks are used on the Belair only for 1958. I have 4 of these, they are not new, rather they are used but in excellent condition. The knobs are not cracked or damaged. The chrome is very nice, not perfect but very nice.
For information sake, the knob appears to be the same as the 1953-57 window crank knob but the chrome handle is different.
