SIGNED mr norm tri-power air cleaner for hood tach

i don t really want to do this, but i have 2 of these air cleaners and need a hood tach more than the air cleaner.
this air cleaner is a restored mr. norm's grand spaulding dodge demon piece. it came on the 340 demon gss cars. it has been polished and painted and is signed. it has a k&n filter in it. it s never been on a car since i ve had it. one of these air cleaner s sold on e-bay last year for over 600 bucks, and it wasn t as nice looking as this one and it was not autographed by norm.

i am looking for a dixco hood tach for my 72 demon 340. i would be willing to trade even up for a very, very nice working hood tach. or buy the tach outright.
air cleaner is in northwest ohio
