replacement for buster crabbe coping

I was wondering if anyone could provide me with an option to replace an old buster crabbe coping on a 16x32 pool from 1979.The majority of the sections of it have lifted and are not secure. I am in need of a new liner and my pool company does not have a replacement alternative and apparently with any new coping being narrower will result in a space between it and the old concrete, which I do not need or want to replace. If there is not a replacement, is there any way of repairing the old coping? Any and all information on this would be greatly appreciated.

Not too many people want to take on old pool rehabs.

I know from experience. Check Vastec USA they have helped me. I have sent them pics of my issues and they always have a fix. http://www.vastecusa.com/Products.html. Also try Cardinal systems at http://www.poolsbycardinal.com/bullnose-coping-crgr.php. extruded coping is expensive. That's hy everyone wants to go new! Post some pics.

Good luck
