transmission question

I have a question regarding the '93 buick centuries, I recently realized my transmission lines rusted through a bit too late while on the highway:banghead:
and I am wondering what makes and models will fit my engine
it's a 93 buick century 3.3L 6C fwd any ideas would be great

Well there are some good quality buick parts (http://www.speedyperformanceparts.com/buick-parts.html) which can help you to decide what a certain part can be put.
