Why thank you Ryan, I’m pretty proud of that shaft!
The T400/205/GV w/yoke combo ended up roughly 56-1/2” loooong. As it sits the driveline measures 51-5/8”, with the rear off the ground and the diff dangling it measured 51-7/8” that’s the max number we gave the driveline shop. So 1350 ends, 3.5” tube and I’m hoping enough travel.
GV recommends Lucas 75w-90 Synthetic so we went with the same for the 205. Spun everything including our fresh 14bolt in drive 4Lo up to about 2K rpm.
A couple days later in drive 4Hi ran it up to I'm guessing 20-25 miles an hour until it finally shifted gears, freaked me out with thoughts of running over everything and smashing into the shelving on the other side of the garage!
Glad to report no crashes, no issues, no leaks, thinking this stuff is good to go for now. Here’s a link to a new video running everything at an idle.
