Years ago I went to the local salvage yard and started looking at all the 4 speed's turning the input shaft with the trans in first gear. Low and behold I found one and I think it had the bolt on rear yoke. Any way to make a long story short between the one I found and the one I allready had I made up a 3.09 tran's and it work'd great. The 69 Dart pulled like a tractor. When you left the gate get ready for 2nd gear.
