NY FS exhaust manifolds

[gmc 2500 4x4]

fs. i have a very nice set of manifolds i bought for my '87 1/2 ton 4x4, and are the wrong ones. i'm thinkin they are for an '88? these have extremely minor rust, no cracks,no pits,factory heat shields still in place. one still has the tube. studs are there .#14093651 LH, i think the # for the RH is under the shield. use your judgment in the pics. the 02 sens is no good.$100.00 plus shipping from 14063.
