Polystyrene coving larger than 132mm?

[lawsos01]

A few years ago I bought some large polystyrene coving from Focus DIY stores for my living room. I recently had to rip down the coving from one wall to replaster. Focus have since gone bust and I cannot find the same size coving anywhere - any tips?? The largest on I've seen anywhere is 132 mm but I need slightly larger (unsure of the exact size). Otherwise, I'll need to rip the whole lot down and start again!

Thanks in advance!

There is usually only two sizes, 90 mm and 127 mm. Ive not heard of any bigger to be honest.
