totally agree with this one..
i highly doubt you will get a half cut for 2k and if you do, let me know and ill buy one with you.
no matter weather you know how to weld or whatever, you still need to buy/build a diff which is about $1500-2500..
at the end of it, if your going to do a proper job like having coilovers, and the right driveline, with a well built motor, the car will be at the 10k mark when your done..
