Hello, I have a 77 Row Crop SN#338729-C77D, I just pulled it down to replace the input shaft and reseal the hyd pump today and noticed that one of my pinion spiders (?PN# M654) and shaft (?PN# M1101) wobbles around and has excessive play. The other one at the moment seems fine. 
  I'll brace up the tractor and pull the bull gears and diff to do a better inspection within the week.
  
  My big question is where can I find these replacement parts. 
  
  I figure I might as well do a full restore on it while I have it this far down. It is a work not a show tractor so a ding or two or welded sheet metal wont hurt my feelings  <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: --> 
  I may also be in the market soon for an axle housing, I noticed a leak a short while back and when I cleaned it off real good today I found a crack in the mounting flange where two lock washers cracked out allowing flex. I use a loader on it for round bails so any repairs have to be reliable and safe.
  
  PS. I had found this site when I was looking for the correct paint colors for it yesterday. Thank you all in advance.
