i have a 79 ford f 100 4x4 351M and my exhaust is leaking on the pass side where the header and exhaust pipe meet and i was wondering if there is a gasket in there or not and where could i find one its hard to explain what it looks like but its flanged with 2 bolts that connect the pipe most the ones Ive seen have 3 bolts Ive looked every where for a gasket for this and cant find one
