I thought it was 69 but I am working on a 70 charger late model year build and it has the LH threads. So when was it phased out?

I thought '69 was the last year too, but guess some '70s got leftovers.
My '70 cuda had RH threads all the way around.

This 70 was built in 71 so its even later than I was thinking.

My first car - a 1970 Cuda 340 had LH threads on one side of the car & RH on the other. I don't know the build date of the car, but I think it was early. Guy worked for Chrysler & ordered it as soon as the order banks opened. Car did not have the rear sway bar either.

I have an issue of Consumer Reports that says early 70 'cudas did not get rear sway bars as they were supposed to. My 7/30/70 'cuda does have one.

My '70 cuda was built 10/30/69 with no rear sway bar and all RH thread wheel studs.

According to the Factory Parts Manual the '71 change was across the board, all makes/models including the 7/16" A-bodies.

I am fairly certain my first car, a 72 4 door dart had LH studs. Memory could be wrong or maybe it was an early build 72.
I also had a 70 duster with them.

383 Cudas & Challenger R/T's were supposed to get the rear sway bars also according to the vehicle brochures.

The TSB above was dated August 10, 1970 so it was already into the 71 model year... work
