help T-5 experts? shifter a bad choice??

[90dpscoupe]

Ok, actually the hurst shifts good, but my tranny has been whining for a while now, well the hurst doesnt have all the rubber in it, like the stocker, therfore im getting a nasty noise, "drive noise" and i was told from my friend, it is synchros? it whines only 1st-3rd, i guess a rebuild is gonna be needed, about how much should this cost?

It only whines when im giving it gas?? someone help im gonna have to put the stock shifter in now cuz i cant take the noise, and i already cut the rubber boot. Man im stressed...what should i do?
