To be clear :
First series has the split windshield .
Joe can set you up with whatever you need .
54 and 55 1st have one piece windshield.All you needs know is :
Do you have a two piece windshield with a divider or not ? .
If two pieces of glass you'll need the 1947 ~ 1954.1 visor .
Yep! Nate you have no idea how much I wrestled with myself calling into question your statement. I am a fan of your "been there, done that" knowledge.And, there you go .
My old worn out mind no longer remembers important details like this .
The 1955.2 has a dog leg windshield as it's a "Task Force" truck not an Advance Design like the 1954 & 1955.1 .
