Well 6k is not in the trans budget this year, I was hopin to come in under 2k so time to go another way, In mud racing we don't torque up on parts like drag racing,just not enough bite on the hit, so a 904 my live longer in this application, does anyone know how much shorter a 904 case is from the bell to the back of the case where the sprag is? I may be able to move the fire wall back where the dist is a few inches and set the engine further back, this is a good option for me as we are way to front heavy now and it would save me from making up 2 new drive shafts and a transfer case mount
