“We were looking for a cartridge that not only matched the bottom holes but that would have the splines & you knew our cartridge had an additional piece which would not have spines on the new replacement
We received the replacement cartridge yesterday; we replaced the old today & happy to say it fits perfect.
Thank you for your great information and the speedy shipping. Should we need other supplies in the future, we will certainly contact your business.
