Screw the 200R4, get a 700R4. 91' and 92' were the best years for them. They're stronger than the 200 and have more aftermarket support. Believe me, for the street you'll want that overdrive. And 3.73s are plenty gearing for a street driven Monte. 4.11s are overkill. Its going to be revving high enough with the TH350 tranny.
