Center mount slides are the worst for several reasons.Depending on the clearance and structure of your drawers you could probably use some Blum undermount slides or their tandem undermounts.These go under each side outer edge of the drawer and wrap around the edge or under the bottom panel. .Very good quality.

I went from a 36" cooktop to a 48" range top and I love having those extra 12" to move pots around and I have plenty of space for placing items out of the oven while I am using the range top. No need to worry about having trivets handy, and it gave me more drawer storage underneath. I have cooked on 30,36 and 48 and I much prefer having the extra real estate.

You’ve shot everyone's opinion down so much that no one is going to comment. You want an echo chamber of agreement only. You don’t want to hear that your original is actually better than this expensive remuddle and that you’re not working with a skilled KD. You’re not dealing with the floor height issue and other issues that take precedence. You’re trying the high cost and fruitless route of keeping some cabinets that is restricting you in creativity and results. Again, without working with the right designer. Is the option to sell sell the house still on the table?

Thank you. I live in CAD so was shopping CAD retailers. I should have mentioned that. Thank you for the link. That is certainly something to consider! If they have one, maybe there are more. FYI I’m replacing with flat black.
