Unsilenced BBD 2 Barrel Air Cleaner Assembly?

I have one of those here from a /6. I would like to use it on my /6 but it won't fit the BBD I also have several "more typical" 318 air cleaners up in the attic ( I had 7-8 of them/ I scrapped a few even) and I was gonna cut the center out of one, then cut the center out of my /6 unsilenced base and weld the 2 together.... Under that top it won't be seen.
