WTB: Seat mast/seat cap for Trek Boone/Madone/Emonda/Domane. 135mm - 5 degree offset

Looking for a seat mast/seat cap for a Trek Boone. Newer Madone/Emonda/Domane work too. Must be the 135mm length with 5 degree offset.

Looks like this but with 5 degree offset.

Thanks

No bites? I suppose it's just not the kind of part many folks have in the spare parts pile. I guess I may need to get my head around Trek's full retail price on this part $$$$ :mad:
