Default What rear ratio do I have

'89 6spd. Is it 3.45 or 3.54? I heard somewhere that the first year 6spd had 3.54???? Thanks

I'm going to say 3:45's. A well informed L98 owner will be along soon to either confirm or deny. :thumbs:

It is most likely it is a 3.33, but it could be a 3.54. Look under your center console lid and post all 3 digit RPO code's that start with G

My '90 L98 6sp has 3.33. The ratio is stamped on the bottom of the diff housing, at least on mine.
