Are you sure it's from a '42? That's a rare car...I'd hate to see a hard-to-find piece like that butchered to fit a truck cab, when there's probably 100's of '42-'47 truck hoods available with just a little hunting...
Well, I hope you're not over 5' tall, 'cause there isn't alot of room inside a Model A to start out with, and with a chop, channel, and section, you'll never be able to get in it!
There was a discussion going on over at the Tri-Five Chevy forum about doing this...in the thread about a 4-door to 2-door conversion, a couple of the guy's said they were thinking about trying it!
Apparently, someone already did!
