318 Poly Exhaust

just realised i checked the wrong aplication somehow i got into my head that it was a coronet,but anyway,the huth catalog showed a "cardnumber" but it wasnt anything that could be found in paperform and it was not to be found in the computerlibrary either so i gues the patern may not ever have been available to mufflershops for bending on spot:( i may be incorrect about this but where i work there is a pretty darn big library over this kind of stuff and it surprised me that i could not find it.
