Shutting off the engine and putting the shifter in neutral did nothing to unlock the rear tires, so it got removed. turning the engine by hand at the harmonic balancer while in gears causes the remaining upper ujoint and shaft coming out of the transmission to move. I did not want to run the car in gear with the drive shaft out , but i assumed if it would spin by hand then I would be fine.
The shifter has a red cable going from the B&M to the trans and I have headman headers on the car.
Lol trying to give yall the needed info so bear with me, I had no idea what all to provide
