Throttle body bushing - David Koldos
Stingraynut:
Yes I did think about it - but at today's rate that's Aus$388, and then there's the shipping - the major places like Ecklers seem to charge heaps for that - say $45 - we're up to Aus$433
Then it arrives in the country and you get charged GST and Duty, the GST is more than 10%...... you can guess how I know, I got hit twice last year - thought I was saving on the shipping by making big orders. A big mistake
Say Aus$140 for duty and GST- total cost could be around Aus$573
Luckily my third order last year - a complete weatherstrip kit including window rubber in/out, and steering wheel, was marked with a low value, so no duty to pay, but the major places put the true value invoice on the package.
My choice is US145+$20 shipping (Aus$214) for a TB with bearings - better than original, sounds very good to me!!!!
David has asked for pics of my TB to make sure he sends the right one, and requested a further close up of the RH Side - he seems to be very careful and precise, which is v good.
BTW - There may be about 5 different Tb's for the C4 - 85-88, 89-91, 92 - 93 , 94 and 95 here's link to pics of them - http://www.hotrodlane.cc/throttlebody/throttlebody.html
I doubt there's much difference, probably just the throttle linkage and /or vacuum port

Yeah I know the duties are rediculus, where did you you did you get the weatherstrip kit from & what was the quality like, aftermarket of genuine?
Stingraynut:
I got the weatherstrip and steering wheel from Contemporary Corvette - http://www.contemporarycorvette.com
The weatherstrip appears to be good and was highly recommended by good guys on the Corvette Forum. Got the views of several people who have used it and they reported good results and longevity. Just post a question there and you should soon have some info on the quality.
I haven't fitted any of it yet because I'm doing a slow think about a respray. I ordered because the Aussie dollar was so good at the time and they had a special on a full kit. I also bought the door/windows strips too - then the Aussie dollar went even higher - luckily this order was not hit for duty. ;41
The other reason the w'strip isn't fitted yet is that I only have one leak - and it's BAD - it's taken me a long time to work out what it might be - the join between the side roof rubber and the side of windscreen rubber - it's fine in ordinary rain, hardly a drip, but in the Cairns Wet Season I was getting something like the flow from a garden hose turned on about 25%.
I was reminded that they also make swimming pools out of fibreglass. I want to be very sure when I glue the new w/strip on that I get it right and cure problems like that.

I fitted the new throttlebody yesterday - all is now smooth!!!! It probably feels no better than a new one, but it will last forever!
I normally don't report success so quickly but in this case I can't see that anything will go wrong now - so it's a big thumbs up for David Koldos and my new improved TB
The TB comes bare and all plates TPS and IAC have to be transferred over - I bought a complete gasket set from D Koldos. Then the base idle and TPS voltage have to be set - as per the tech tip by Lars Grimsrud on the Corvette Forum.
I did this procedure last year and it made a big difference - the base idle was way off which I think then upsets the TPS setting etc.
