I only need to know what 1st and 2nd are as I have straight cut close ratios for positions 3rd 4th and 5th.

1st - 3.909:1 (same on all of the 1997 Mk1 puntos inc the 16v 1.2 but cant speak for the 1.6)
2nd - 2.238:1 (same as the TD60 and TD70)

[Slim]

Thanks for that. Was hoping 1st was 3.545:1

Cheers

3.5:1 is from a Fiat coupe 16vt gearbox

Any C510 type gearbox has interchangeable parts...

Punto turbo
1st 3.909:1
2nd 2.238:1
3rd 1.520:1
4th 1.156:1
5th 0.872:1
reverse 3,909:1
final drive 3.353:1

Uno turbo
1st 3,909:1
2nd 2,267:1
3rd 1,469:1
4th 1,043:1
5th 0,875:1
reverse 3,909:1
final drive 3,353:1

list of vehicles equipped with this gearbox can be found on the quaife website

QDH2K has been designed on the C510 gearbox so all these vehicles have it...

Common solutions over here is using the 4th from Uno turbo or 5th gear from a Tempra as it has longer ratio...or crown wheel from Bravo 20V..
Actually many years ago Novitec was selling a "longer 5th gear" for lots of money that was nothing more than a tempra 5th gear..
2nd/3rd from various Alfa/Fiat models depending the use etc..(search for Fiat fiorino 1.7TD gear ratios...they are the strongest of the family in order to support the diesel torque...many used 1st/2nd from this gearbox as it is ideal for drag use)
