OEM 1968-72 Chevrolet Camaro/Chevelle/Impala/Nova SS 396/427/454 LS3/LS5/L36/L72 Air Cleaner Pre-Heater Stove Pipe Flange. This is an original 48+ year-old pre-heater exhaust manifold stove tube adapter specific to the 68-72 396/454 models that has been media blasted to bare metal, then coated with high heat ceramic low gloss black. It retains the square insert with screw hole where the tube adapter inserts into the stove and is retained with a screw. The mounting support is fully intact as well and in excellent condition. This particular piece is stamped FABCO by the screw hole.

These are extremely hard to find - especially in near NOS condition. Back when new, these were typically discarded in lieu of presumed performance enhancements (especially once headers were installed). This piece was removed and stored for nearly 50 years and shows that it was hardly used.

This piece presents very well and will enhance your restoration. Best of all, it is a rare and genuine GM part!
