sorry if this isnt the correct location for this.

i have currently a 04 silverado rclb and am about to swap to a cclb and was wondering if anyone else has done with swap and if so any pointers? ill be making custom crossmembers as this truck will lay down when its all said and done.

mainly worried about the driveshaft as it will have to be extended a good deal with laying the truck out how will this super long drive shaft hold up or will i need a 2 piece
