Ok ive read over some posts over on d-series about changing the final drive to create a higher output tranny for the d series motor, I have both a SI box, and a ZC box, Id like to put the si final drive into the zc tranny but kinda scared to crack it open to loose stuff, and not being able to get a perfectly good tranny back together, do you have any pictures, reading material, etc so I can have a lookover before I go-ahead with this process?

Will changing from zc final to SI final Will I really notice a difference, and will I have to change my axles again?
