I'm looking for a base to use on an Eddy AVS2 with the Road Runner unsilenced top.
That's 12.75 - 13.00 across, with a 5 1/8 carb air horn.
Stock looks to be about even height, maybe +1/4" (filter higher than air horn), don't need a drop base.

Been beating the heck outta the interweb - Summit Jeg's Manicini Ebay Amazon Proform etc etc.
Even tried plastic, 12", nothing. 11" is too small.
Only thing I can find is a Proform assembly for Fords at about $70, but all I need is a base.
I thought I'd find something - I can't be the1st guy to this party, right?
