[AJD] 1931 Unstyled John Deere D Exaust Pipe and Seat

[Kropelin]

Greg, 
Thanks for the info about the exaust pipe. All I have left is the elbow .
and am going to order a welded pipe from my steel supply house to replace the missing section. Please let me know if by chance you run across a seat spring as well as the bracket that holds it to the gear housing. My next project for this "D" is to get the pistons unstuck, All I am going to do is remove the block and press out the pistons in my press I hope that the bore will clean up! But if it does not would you or anyone happen to know if oversize pistons are avail? And what might the cost for such a purchase may be? 
Thanks Kevin
