You can find donor boards of this type for like 10 bucks on AliExpress. Why bother buying new "compatible" components ?

Scrap boards are "must have" for a service.
Also, some 0 ohm resistors can be replaced by a simple tiny wire.

first time doing one, just needed some insight. Now i just feel silly!

Many Thanks all!

You're welcome.
Make stock of various scrap boards, if you plan to deal with Apple repairs.
Some components can only be removed from donor boards...
