Thank you Chip! Yes it is metal, I think it is more strong than use plastic.
Meyer snow plow did not have the light on the snow plow. I think they were added a the end of the 60's. So I don't think to put them on mine. Were I grew up, there was a Jeep Willys, ex-WWII, with snow plow, I don't remember the brand.
The half cab on the kit is similar to the Meyer one, but the roof and door hinges are different, I think they made so for a easy assembly. Also there was different brand that make half cab or a full hard top with different configuration. Also Jeep sold its own cab/hardtop.
