I've got an 84 5ksT. I was wondering if the kh manifold is the same as the mc. If not did it have the same problem of cracking as the mc did? Can it be repaired by welding? How reliable would it be? The 85 mc(later half of 85) did that use the kh style or mc style (if they are different)? Will the 2 piece mc manifold from the 200t fit or will I need to use a diff downpipe?
