I want to replace the worn half shafts on ny Mk3 Cortina fitted with a Mk4 Cortina Atlas estate heavy duty axle, I've replaced the Capri LSD with a Blackline unit so need to source some new shafts - group one with 18 tooth spline Quaif can supply the shafts and hubs custom length, question, do all the heavy duty axles have the same wheel bearing set up, length, bearing position and diameter?
