Tree, I would be very interested for around that price!! I don't have a spare 3400 TB, but I could take mine apart and put the 3100 one back together to keep me running.
But shipping one up to you may not be as cost effective as you just getting one. I got mine for $15 shipped. I don't know how cheap you can get them?
Mine I did have to modify it for the IAC passage to be open to the main TB bore. Some 3400 TB's have this done stock, some do not. If you would supply the TB, I'd prefer this style for mine if you grab a few and one has this. I don't have an air compressor anymore to use a die grinder to do this now. I can get you a pic that shows what I'm talking about if need be.
What do you estimate total price would come to if you supply the TB shipped to the states?
I take it comes with a new TB plate too?

Thanks for the offer I'm very interested!!
