Do you have a header mount glass pack that is shorter than 24inches maybe 2 inches shorter, has a header 3 bolt flange for small block ford 289 ci engine, 3 inch from bolt to bolt and a 2 1/2 inch inlet. Going on modified 1952 M38 Willys Jeep with Ford 289 ci Engine . 25 inches from header to wheel is all I have for room and I prefer not taking it to muffler shop. Thank You John
