[mtg6486]

im going to be upgrading my fuel system with the racetronix fuel pump kit http://www.racetronix.com/RX-F98-FPKG-2.html and 42lb injectors.
i was thinking of buying these ones http://www.racetronix.com/17113813.html
my question is will these fit my 98 ta and if they dont how do you know which ones will ive never bought injectors before so any help would be appreciated
