Jan 2006 ------------------------- Muffler numbers for 62 Daytona V8 ------------------------------ Arvin # 1841 was the stock muffler. NAPA Soundmaster Muffler # 723. Maremont # ST44 was stock muffler; # 87003 was the Cherry Bomb muffler. All those are 1970s numbers from old catalogs I have. Hopefully, an understanding jobber could change them over to current stock numbers
