CASE 3000 Toilets Replacements

I have 7 old CASE 3000 toilets through out my house and would like to start replacing them. Is there a brand which will bolt up to the existing bolts of the CASE 3000 toilets or will I have to start from scratch?

3000

There is NO replacement for them, but you also do not have to start from scratch. You must open the wall and remove the upper hanger bar, then install the necessary threaded rods, nuts, and washers into the upper openings of the carrier. Once that is done, you can use any conventional wall hung toilet.

Thanks! That's what I thought. I will have to get my plumber to do the work.
