Depends on your goal. Are you keeping it original?
I kept the original windshield AND the crank. It is one of the most talked about items on my truck at the shows. Mainly because it seems EVERYONE does what you are thinking about doing and you just don't see the original cranks anymore. Not to mention, there are only a few vehicles with this option in the first place.
If you decide to stay original, I'll help you out on the info you need.
