Different sized arm for 39-050

A handy person from Ciovis Californa says:
You have a crank that is the same as the I have.
the only thing is the length.
new one is 6 1/4 long this one is 5".
will that make a difrount.

Thanks for posting! I'm afraid we don't have an alternate version of the 39-050 with a longer arm. I don't think the difference will be too extreme, the worst that will happen is that your window might not be able to open as far.
