Rebuilding tranny and have question on new gears.

$100? i saw the d&d kit for $189

i rebuilt my trans(bearings/synchros/rings) for about the same, $190 plus fluid and replaced 3rd gear since it no longer had teeth. the cost of replacing any gears prolly would buy a whole new trans. if you change one gear then you need to change the whole cluster shaft since its all 1 piece. 3rd ran me over $100 and the cluster was bout $300.
