Not Ranked
Great summary from Davids school of hard knocks. I must point out his tubular shafts that twisted were driveshaft tubing which is too light on tubing wall. The diff is a big torque multiplier and you need to do some simple maths with your ratio when calculating a tube wall thickness. Then throw in a factor of safety (FOS) on your numbers. Use seamless DOM mechanical tubing.
Then there's 3159, do we know what diff or upgrades that was running or were even available?
