I currently have a T5 that is set up this way.
1st 2.95
2nd 1.94
3rd 1.34
4th 1.00
5th 0.63

I want to replace it with a T56 and see that the one out of a 93 has very similar gear ratios.
1st 2.97
2nd 2.07
3rd 1.43
4th 1.00
5th 0.80
6th 0.62

Can I swap out the 0.80 5th gear for the 0.50 gear found in later models 6th position? Does it fit in that spot? If it does, is it a lot of work and would I be looking at it causing me any trouble later on?

Thanks
