Differences in N/a and T-II Drivetrains
 

Would someone out there who's had experience with this tell me the differences between the N/a 13b and the T-II drivelines. I'm interested in everything but the motor basically. How do they compair to eachother as far as the power they're supposed to handle? Do the transmissions have the same bellhousing patterns and input shafts? What is the stock gear ratio on an 87 N/a 5speed, and is it a posi? I'd appreciate any input you can give me, or to point me to a page where it's all listed. I spent a few hours on the search, but didn't come up with exactly what I was looking for.
Thanks alot,
Jon
