Off the top of my head the 2nd gear is like 0.5% taller and double syncro. 3rd and 4th gear are the same close ratio as the evoIII 3rd and 4th gear, except that the evo1 gears are only single syncro.

If you plan on using that gearset, it would be nice to freshen it up and toss in new syncros on all the gears. Syncros are fairly cheap. I owe you a favor so if you decide to do this, bring me both shafts and some new syncros and I can install them for you in less than an hour.
