Can I reuse rear axle nut?

[markmalin]

My 85 Carrera has the castilated nuts for the rear axles. I bought replacement (non-castilated) nuts from our host, but they are not the right size. Since the old nuts are castilated and use a cotter pin, is there any reason I can't just re-use the old ones??

Thanks guys.
Mark.
