BUT.... once you have all the pading...ect off the metal structure under it becomes very flimsy. some reinforcments may be inorder (just to make it a little less flimsy) depending on how "smooth" and clean you want it to look you will have to fill in holes (weld in patches) and do some filler work to get rid of the spot welds and ripples.
Its a very good base to be creative with to. you could add sections to make room for more of a guage pod...ect with the added benifit of it already fitting into the car.

Taking off the foam is best done (i felt anyways) by cuting it up into sections with a sharp blade/copeing saw and scraping/prying it off in larger section (a few inches at a time). then go over it with an assortment of wire wheels to get the rest of the lingering foam/ glue off. then start preping for whatever you going to do.
