I know several of the guys here will happily help you with that last issue, but the cost of shipping it to them & then to you will make it not worth while really. I know it isnt ideal, but check this out:

$20 + ~$10 shipping from ebay. Otherwise, you could use the GPM 3906 alloy bellcranks same as I have, then just use a normal servo saver on the actual servo ( 'Kimbrough large gas truck' model works well ). Heres the GPM:
silver,
blue
Not quite as sexy as the GH, but if you give the silver one a bit of a polish it'll look pretty nice I reckon?
