Thanks everyone for your responses. Based on the feedback I'll likely retain the wing windows. Finding doors for a COE would like be a difficult and costly endeavor.
Just as an FYI, if this was a complete truck I would never consider a mod like this. I've restored many vehicles back to original condition and appreciate the authentic value. However, I started with just a cab, and it was very, very rough. I had to source the fenders, etc separately. I'm constructing a car hauler with this cab on a motor home chassis. Looking forward to hauling cars without having to hook up a trailer.
Also, I was unaware of posting similar topics on two different forums. I thought is appropriate since the topic of doors is generic, but the COE doors are unique. I won't do it again.
