Technical 1940 Ford Dash into a 37 coupe

I have a finished out 37 Ford with a crank out front windshield. I was thinking about swapping in a 1940 dash. I'll have to deal with the windshield crank issue obviously but are there any other issues or is it more or less a bolt in deal? Since my car is already painted I'm not looking to have to weld or do heavy modifcations to the car it self.

Thanks

Mike

 

Not a bolt in. The flange on the cowl is different because of the window spacing.

 

Thank you! This is valuable information.
