As stated, none in 80', but in 81' you could get a 4 speed with a Chevy 305 only. Was basically the Camaro drive train installed in the T/A, and they did not use the side splitter tail pipes either. From factory the 305, 4 speed cars came with straight pipes out just like the Camaro. Many added the splitter tail pipe extensions, but it did not come from factory that way.
