[DOAE-9430-G appears on both BOSS 351 and 351C 4-bbl right side manifolds. D1ZE-9431-BA is the part number for the left side for both engines. BOSS 351 exhaust manifolds measure 2 1/4 in. at the exit port. 351C 4-bbl exhaust manifolds measure only 2 in. though I’m sure many BOSS 351’s received the 351C 4V’s manifolds from the factory. Refer to Mustang Monthly 5/93 for more info.
