What was Mr Norm up to in 1970?

We all know that he was busy stuffing big-blocks into Darts in 1967-9, and his GSS Demons in 71/2 are well known but I have never heard a peep about what he was doing, if anything, with A-bodies in the 1970 model year.

Was there a 1970 GSS Swinger? I've never heard of one. Was he too busy playing with the new-for-70 Challengers to worry about the little Dart that year?

Inquiring minds would like to know! :D
