Dangit lol. I sold mine from the 73 parts rig I have. I put it on a newer econonoline van because ford stashed it behind 13 hours and it can go anywhere.

Thanks all
That would be great. How much do you want for it? An upgrade for AC is in my future, but for now, I have to keep the original. It's blazing hot here in Houston, need to get something blowing
