i last heard, according to fram, a 1000 piece order minimum for retooling, (i believe the original stuff from the CA332V were destroyed, or something of the such. either way, new tooling is required.) @ $50 a piece. so, a $50,000 dollar nut to crack to get them made. quite an investment. but, you would think if several parts houses/companies went in on it together, and agreed on maybe a minimum price, you might be able to pull it off......
as far as old filters closing up, i have an original 70's piece i acquired recently, and the hemi ran just fine breathing through it. but i also ultrasonically cleaned it as well..............
