Just thought I'd share that currently someone has 364 injectors on ebay listed as new old stock!
https://www.ebay.com/itm/NEW-OUT-OF-BOX-Bosch-0280150364-Fuel-Injector/184011419315
They are asking $20 for each, this is a bargain price if they are really new old stock. These are drop in replacements for the 3.2L factory 158 injectors, the 364 differs only in that they have metal tip instead of plastic.
Enjoy!
