Got a 76 4wd truck, was gonna replace the cab with a 74 2wd. I am sure the tunnel in the front is a little bigger. The problem is the carpet jute in glued down,and the carpet is glued to that, I mean glued down.I tried to scrap it up but it is gonna take some time.just wondering what the in's and out's are.thanks for reading this and thanks in advanced for any help.

You could apply heat to the bottom of the cab and see if itll loosen up
