You should really try doing this swap your self. I hear its one of the easier swaps to do. Plus you could save your self a ton of money. Just get a couple of friends over and plan out a saterday and buy a 24 pack and have the radio on and just have fun and enjoy doing the swap. Besides you will feel better about doing the swap your self. Just my .02 if you still dont feel up to the task contact Datsun Dynamics on rt7, Altered atmosphere in md, OR better yet. Join the 240sx forums around here. Plenty of people around here have done there own swaps and im sure wouldent mind lending a hand or so. here are 2 forums you should join,
