2.94 gears with a four speed.

Ohno,not the 2.44.
Oh this will be a huge improvement;26.6% That is the equivalent of 2.5 rear gears, say from 2.94s to 3.73s.
But;
you neglected or I forgot, to ask; Will your mainshaft accommodate those unbushed gears?I'm pretty sure it will, But I don't know it to be a fact.
I have a regular case and tail housing sitting on shelf in garage, these are in addition to my complete 2.44 box. I thought all I had to do was buy a regular a833 short tail shaft main shaft and use my non trunion style tail housing with the 3.09 gear set. Is this correct? Ultimately I will have two complete transmissions, one 2.44 box and one 3.09 box.
