an 89' Ghia diff is most likely going to be a 2.77 ratio lsd, you'd be going backwards..?

It would want to be September (or thereabouts) '89 model or later in order to be the 3.08 LSD.
To correct the speedo, the speedo sender gear in the transmission will need to be changed. This small part is inexpensive and widely available even at wreckers. |

EA2 Ghias actually had a 3.23 lsd, sphell has one in his car which he has upgraded the gears to 3.9's. No such thing as a factory 3.08 LSD boys. :P

Yeah i had an EA Fairmont diff which was 3.23LSD and also had 28 spline axles! If you go for a more wild diff ratio (non-factory ratio) you can also correct the speedo with a digital speedo corrector kit from jaycar electronics. |

I recently went from a 3.23 free wheeler to a 3.73 LSD. To correct the speed I built a "Speedo corrector kit" from Jaycar and patched it in at the guage cluster (before the speedo and ECU - direct from the speed transducer). Then I just select the % error, and it works fine! Fixed all the shift point problems I was having too
Edit: Here's the Jaycar kit details... "Digital Speedo Corrector" Cat Number: KC-5380 $44.95 ...and then just wack it in the HB-6016 jiffy-box ($3.25).
