Gearbox - Avanti built, using Uno turbo gears

I bought this gearbox from Rob W from this site with the intention of fitting it to my hillclimb car. However, it never got fitted and next season I want to use a straight cut dog box. Therefore, I need to sell this gearbox to try and raise some funds towards the dog box.
Avanti who are renowned Fiat tuning guys, built the stronger Uno turbo gear set into an X19 gear box casing/final drive. The gearbox has done less than 3000 road miles. I have listed the gear ratios below.
This is a fairly rare opportunity to get a stronger box with syncros that work. I am looking for offers over £400 (this is less than the cost of 1 straight cut gear!!)


Uno Turbo ratios:
Gear G Ratio Overall
1 4.091 14.64578
2 2.235 8.0013
3 1.469 5.25902
4 1.043 3.73394
5 0.863 3.08954
Final Dr 3.58



Standard X19 ratios:
Gear G Ratio Overall
1 3.583 14.607891
2 2.235 9.112095
3 1.454 5.927958
4 1.042 4.248234
5 0.863 3.518451
Final Dr 4.077
