Yes JCL, your right. I was discussing this today at work with an experienced automotive fabricator and the rear certainly would be put under too much stress, so I will have to keep the front drivetrain and therefore the 4.11s unfortunatley.
I removed the clutch assist spring on the pedal today, and it made the clutch only slightly heavier if at all, but you can feel the clutch so much better and it makes it much better to drive.
The more I drive it, the more I love the manual.
I put some wheels on it yesterday. I will post a pic once I work out how.
