Waste gate

[Efraim Gavrilovich <egav@wireless2000.com>]

Hi,
Does anybody have or can recommend a place where I can get a used or
reconditioned 88 5ktq waste gate or diaphragm for it? One place in Florida
offers diaphragm for $95, is it too much? Is it better to replace a
diaphragm or 
should I keep looking for a good used waste gate?
I also need a trunk lock, an antenna (it doesn't retract) and a rear door
handle.
I will appreciate any suggestions.
