If you want to stick with the 4.3, for power reasons. I will swap a perfectly good tight no whine 100K 4.3 LSD out of my 84 for your 3.73. I am going 7MGTE so I don't need the lower gearing for acceleration.

Yes, any of the diffs are interchangeable, but to get the speedo working with your 3.73, you are going to need to dismantle the back half of your tranny to swap gears.

Double post! I really only want the gears. I have another complete truetrac diff, we can maybe make a deal if the gears go one way and the complete diff goes the other.

BTW, you can get brand new 3.7~ gears from Toyota. I have not heard of aftermarket ones. Anybody else?

Are you saying that Sean can get aftermarket 3.73 gears? I already have a 4.10 trutrac diff built up in the box. Can you get me his #?

Lowest numerical ratio aftermarket I have seen is 4.10. The 3.72x7.5 had such limited applications.

I will call Sean tomorrow, thanks for the info. I also see a lot of used 3.73 diffs on the internet part searches for $100-250. Would rather have one in someone's hand that knows what's what.
