Bass did a hell of a job blending a 32 lower dash to this 34 to fit in a model a http://www.jalopyjournal.com/forum/showthread.php?t=336494&page=38
My buddy pulled a 33 dash out of his 30 coupe when he redid it a few years ago, I liked the way it looked but it was not my car. You do not see it done much so if you have one go for it, you will love the way it looks, his was beautiful, he went with a 32 dash, like thats never been done before....Jim
