Finding a T/A in a 4-speed is not easy in the 77-81 models on here. I did a quick search & found a few T/A's that caught my eye...
2356884 & 2359003. The 2359003 may not be your style, but it has a built 455 & a 4-speed... she is a "71" which I dig. For kicks, check it out... she is 10K. The first one is a virgin/all stock... very nice looking car w/ one repaint; but unfortunately she is probably an auto.
