Hi 300 folk, Well, the 413 transplant into my Pace Setter is one of those 'one step forward and two steps back' affairs. I finally got to where I could put fluids in it and two fairly familiar MoParly leaks immediately made themselves known. 1) The pushbutton shift cable where it enters the transmission housing. Where do you get a new O ring for the cable? Does that really stop the leak or are there tricks you have learned over the years to stop this thing from leaking? 2) The rear of the rocker covers, which are the old 4-stud variety that likes to 'canoe' when attached. Oil is pouring past the nice new cork gasket on the left rear corner. Should I go with a cast aluminum non-stock rocker cover set, or is there a secret 300 Club way to get the oil to stay inside the cover with the stock ones? All advice gratefully gobbled up. Hope you all had a good Thanksgiving holiday. Cheers, Doug Jones Boulder Creek, CA, just over the hill from Jett Ranch
