Ernest,
For my 20B, I initially purchased an LS1 throttle body off ebay, which
was a tad bigger than the Mustang TB (70mm if I recall correctly).  I
accomplished the return spring mod by removing the stock LS1 spring and
replacing it with one from the Mazda TB which was wound in the opposite
direction.  I ended up not using it after all, so I can't say how it
works in the real world.  You might be able to find an appropriate
spring (wound the desired direction) from a good hardware store, or head
for the wrecking yard.  I don't think I would attempt reshaping the
Mustang spring. =20

I measured the ones I have across the opening in the bottom, and it came

out to 60mm.  Did I measure it in the right place?  The intake end seems

to be slightly larger.

BTW, how did you reverse the spring?  Can you just bend them around to=20
the proper shape?  These springs on this
BMW throttle seem to be pretty stout.  I don't think bending them into=20
shape would be trivial.
