D4-7U tools

I'm searching for an idler wrench---4A45 or 4A0045, 2 3/4 inch. My crawler is D4-7U10608.  email is [email protected], phone is 970 247 5415. 

Am also needing parts for the hydraulic control unit (serial number 6W6792) as follows:

7F3585 lever (1 item)

5F1680 plug (2 items)

7F7483 cover (1 item)

These items are shown in the diagram on pages 36-37 of the "No. 44 Hydraulic Control For D4 Tractor Parts Catalog".

I have an oil cooler core taken from a D4-7U radiator. This oil cooler was disconnected from the engine so I don't know if it leaks. External condition is good. Let me know if you want to buy.

I might possibly have one in my bucket of clunky wrenches (kind of doubtful). From my own experiences, I keep a straight one, and angled and a modified water pump wrench for a 13000?series engine.
In a pinch, I have gotten by using a trusty 24" Crescent wrench as well. Happy hunting. JM
