help with how to remove shower drain

I have a home in So California built in 1969 and I am removing the fiberglass based modular shower to replace it with something that isn't gross! I have a concrete slab home and the shower drain appears to go directly down through the shower pan into the plumbing. There was nothing below the top grate but an open hole, no strainer and the ring around the pipe is so coorroded I can't tell how to remove it.

I am afraid of damaging the plumbing in the slab as it looks like very little pipe is sticking up above the concrete.

Any suggestions on hos to remove the existing drain collar and get the shower surround out without damaging the drain pipe would be greatly appreciated.

You mentioned rusty pipe and 1969---so I figure you have iron pipe--

Here is how I usually do it--cut out the fiberglass pan as near to the drain as you can without hitting the actual drain cup. I usually make a series of plunge cuts with a skillsaw to free up the pan--

A sawsall would do the same,just cost you a bunch of blades---

Once the pan is gone you should have a pipe with some fiberglass --using a sawsall with a metal blade --split the fiberglass (and the metal drain cup--Which is packed with lead) until you just touch the old drain pipe----drive a big screw driver or chisel into the split and open up the drain cup--

The old drain cup and bits of fiberglass should just lift off--Done--10 minutes--Mike--
