Try FIC in Cumming, Georgia (fuelinjectorconnection.com) or injectors plus. Both sell refurbished Bosch III injectors for your TA at really reasonanble prices. I bought stock, 19# injectors from FIC at about $20 each for my 1991 5.0L TPI. My originals wore out at 150K miles and replacing them cured several performance issues I was having. Talk to them - they will help you with selection and installation methods.
