Starting to get a little frustrated here! I had to switch trannys in my 66 Chev. Put in a three speed manual that came with the 230 motor I bought. Had to have driveshaft shortenend due to longer tailshaft...got it all back in, but can't get the shifter levers to go into a neutral position. I did have the sidecover off. Is it possible I didn't get something aligned properly when I put it back on?
