[urq] Throttle Body Shaft Linkage swap

Thanks. I was able to take them apart.  Turns out not only the shaft was
longer on the 5000 one, but also larger diameter, so cant swap them.

I'm working on adapting the end - not trivial.  

Surprising I have not seen anyone complain about issues with interference
between the throttle bodies and fuel rails when doing EFI conversion.  The
cable end smashes into the 034EFI fuel rail on every throttle body and
manifold combination I've tried.  The only one that is close is the Ur Quattro
TB where I could bend the eye that the cable end fits in.  No way to get the
5000 manifold and TB to work with this fuel rail.

No BTDT, but in essence you are going to end up with shorter shaft with 
slot for TPS. Wouldn't be easier to cut and file the shaft to suit, than 
to remove butterfly and all that. Even if it fails, you can always do 
the swap. BTW, shaft is one piece, and 2 sunk in screws hold the 
butterfly. Must clean the shaft before removing, and adjust butterfly 
and Locktite the screws after the swap.
