Arie, it looks like the closest axle we have that matches your axle measurements is the Trailer Axle w/ Electric Brakes # e73SR. This axle has a 6,000 lb weight capacity, has a hub face to hub face measurement of 86 1/2", a spring seat center to spring seat center measurement of 71 1/2".
You might be able to use this axle with a longer hub face measurement, but you're going to have to reweld your spring seats with # TRSS300.
