Rack and Pinion Sterring BOOT

Anyone know where I can buy one of those split, universal boots for my 1988 Acura? Need it for the drivers side rack and pinion unit. Used to be able to find those everywhere. Now seems hard to find? I do Not want to disassemble everything to replace the boot. I've used the split universal boots before and had good luck with them. Now seems can't find them anymore. Autozone says they don't have it
