I went to put my balance shafts back in after having the block at the machine shop. I made the mistake of taking the gears off the shaft and know I don't know which one goes where. they are slightly different, and the stamped on part number is the same on them. there are other marks that are different. I went to the stealership and they were unable to help, but the guy did try. even looked in the techs section to see if he could find something. I was hoping someone might have a set of shafts setting around without the gears removed, or some insight as to which is which.
Umm if they are the same part number then they are the same shaft...I would assume they are interchangeable.
The gears only go on one way for the intake and exhaust IIRC, so you can't mess that up.
Don't quote me on that...but I think it doesn't matter which is which as long as you have the gears timed properly for the intake and exhaust.
Geeze I wish I would have seen this earlier, about the time you posted this I had my balanced shafts right in my hand. If someone else cant come up with something before I get home, I'll check on it when I get out of work.
Do this....

well heres the deal, if you look them up, they are different part numbers for the intake and exhaust. 90 537 565 and 90 537 566 are the numbers. I have the delete kit if I want to put it back in, or I can machine up a set of neutral shafts if I want to on the lathe.
Delete kit is what I recommend.

It must not make a lick of difference. Mine have the 90537564 as expected, but the other side doesn't match. My exhaust has GF 809 0350 X13
