M&H does a nice repop of this Switch.As that ebay auction ended with a final price of $254.54,I would opt for it.
Auto. or Manual trans made no difference as to the part#'s application for the 1970 Chevelle.

Begining in 1970,all GM Cars recieved TCS,regardless of engine size or plant built.It was a federal Mandate.Yes even Canadian built or Mexico.
Engines that came with or without the A.I.R system still got TCS.From the L-6 all the way up to the L-78,& LS-6.A Holley Carb.and solid lifters had nothing to do with it.
But as you know,most Muscle car owners pitched the TCS system 2 hours after the took delivery of their new car. [img]/ubbthreads/images/icons/smile.gif[/img]
