Trying to build a kayak trailer

[LSUMurse]

I would like to build a trailer for my two kayaks. I was thinking of going to the junkyard and buying an axle off a small car and then just building a frame to fit my purposes.

Does anyone know of a good donor vehicle to target? I'm looking for a simple straight axle around 4 - 5 feet wide. My intent is to be able to tow this behind my wife's little Honda Accord. I've never really bothered to look to closely at axles on little bitty cars and have no idea which may be decent to use.
