What kinds of trade items are you looking for? I don't have the inventory I once had, but you never know.
And I'm about an hour's drive away from you. I don't have that type Sundstrand either, but I'll take it if you need rid of it.
I have the rear rock shaft. and some of the other stuff you listed.
Other wise Lowell has the rest.

If you were any closer I'd be all over that.
FYI Vicki to help your sale let a buyer know there are plenty of parts around to fix that transmission.
Also that doesn't look like a 60 inch deck and to mount on the front a special carriage is needed. I don't see that in your pic.
Easton,
I have one in my ebay store, don't know if it's the one you need but the ebay item number is 204484297182.
Let me know if you have any questions.
