Cleaning up the Dells, still need to find sources for small parts. While cleaning up the intake manifolds, off-sets, (which I guess to be big beef, as there is a lot of material that can be played with). I noticed an "A" stamped into one & "B" the other. I can't see any difference between the manifolds and don't have any info on them, but my guess is that the letters determine left and right. So which is which? Thank's Dave W.

Not sure that it matters but I just checked mine and A is on the 1-2 cylinder side.
