i melt billet.. i am building a 59 fleetside that i shortened up to fit on my old step side.i would like to do a one piece side window and have seen kits available, my question is has anyone done this conversion and is there a problem with wind noise. i have heard that some kits are noisy. i would like to do the yourself approach as thats the kinda guy i am. any feed back would be appreciated, thanks
