transmission experts, advice needed

[urban96]

1st gear in my trans is starting to whine a bitamnit: and 3rd likes to grind once and a while crapola

i had the chance to buy a 87-93 t5 locally for cheap so i figured i would buy it, i know the input shaft needs to be swapped (BTW anyone have one they wanna sell )

this winter i want to try my hand at rebuilding this one so when mine does decide to crap out all i have to do is swap. what are some good recomended kits i should look at

hanlon motorsports, g-force (overkill for my current setup), astro performance?


also what causes it to whine like that? worn bearings?

my trans has decided to do the whine deal in every gear. im hoping that it will hold out until i run into some money to get it rebuilt. im in indiana currently and i have found a place that will rebuild it 250 labor and i found a parts kit for 169 off ebay. the whine is definetly from the bearings.
