Slant 6 lo-profile 4bbl air cleaner
Thanks for the photo credit!
I know you didn't ask for all this, but here it is.
Might help you find one.
Those were out of Australia, pretty common down under.
It's also the same as a Max Wedge top.
It is Re-popped in Fiberglass by Kramer I think.
Filters from NAPA are easy to get, I have the number if you need it.
The Valiant cleaner is not the same, I have been looking for that application with little luck.
It's close to this one, but not the same.
The VNR used the correct smaller cleaner.
