Replacement drawer runners?

[SJP]

My old kitchen drawer units are giving me problems due to the fact that they are over 15 years old now and the runners on the drawers have broken. I cannot find any replacements at the usual places (B&Q,Focus, Screwfix etc)

Can anyone suggest a supplier who would have replacements for these (brittle) plastic type runners a picture of which can be seen here-

That saves me spending £4000 on a new kitchen....lol

Poor runners for a kitchen drawer though. Most have had wheels for years.

I have some like yours - but in a small drawer in a wardrobe fitting.
