I don't know whether the hoods will fit or not, but at £10 a pair complete, it wouldn't break the bank to try.
The seller is Paul Milnes Cycles - a well-established Yorkshire cyclocross specialist. I've been a satisfied eBay customer of his in the past.
Three pairs left. Be quick!
Calmes dans le demi-jour
Que les branches hautes font,
Pénétrons bien notre amour
De ce silence profond.
