I have a very low mile 1973 911S engine case for sale. It is number 6331457. Being a late case, it is the desirable 7R - 7R. I have cleaned it well, and covered it in WD-40 to keep it fresh. All the head studs have been removed, and the threaded holes are perfect. Or you have have the time certs installed. Price is $2000. If interested please email direct to >eurotech@together.net<
