The Throttle Body repair kit no longer exists and I can not find one anywhere. I can supply the fuel regulator (3808522) and I can supply some of the gaskets for the fuel injectors (18-7690), but that is it.
If you want to send us your TBI I might be able to get it rebuilt. There are a number of rebuilders that somehow piece together parts.
I am sorry, I can't be of more help.
