I was really excited to get this but it won't fit without hitting my heater core assembly.

I have an Olds 455 in my '64 and it's just at the perfect height to hit.
It comes with the filter, base plate, and threaded rod and fold-down.
I'd trade this for another nice air cleaner or ? I don't even know what I need/want, but I'd even throw in cash for something.
I paid $96 for it and have included the ebay description.
I just don't want this sitting in my shop.
Thanks!
