Old MFI Kitchen Drawer Runners

[moodytoo]

I have an old MFI kitchen in which the drawer runners have failed. I cannot afford anew kitchen and would prefer just to replace the runners. I would also like to make them soft closing and have them open further.
I have seen these drawer runners on the following site and wonder if anyone can tell me if these can be made into soft close.

Replace the entire draw with a soft close model.
