3.45.

'4th' is actually just an overdriven 3rd. If you feather the throttle at that speed on a flat road you'll be getting 6-7 L/100, so relax.

80 km/h drops the revs to about 1500, and 5-6 L/100 is possible.

The 3.45 LSD was half the reason i bought my Ghia. Enjoy it!!

sees a bit high for 3.45's Im doing 2250 at 100 with 3.89's. iirc was on about 1850 with the 3.08's. Presuming that Ply has an auto.

I would imagine 3.45's behind an auto would be closer to 2000.

manual and 3.45 would be closer to 2100 i think.

mine did 2100rpm @ 100kph with 3.73 diff

either youve got 3.7's or the gearbox has been swapped sometime in the past and possibly the wrong speedo gear has been changed with it (just a thought, but im probably wrong)

3.7s.
With a stock auto @ 3.23 it sits on about 1800 @100. just under 2k with 3.45s, just over with 3.7s.

thats wierd. my au says on the tag 3.08:1... but it definately has a 3.89:1. Its not hard to change a set of diff gears dude.

Ill put money on the 3.7's, its too high for 3.45's in an auto.

As long as your wheel/tyre combo is still 'right' (ie. close enough in rolling circumference to factory), than 3.7's are what you've got.
