thanks guys,

Just pull the blade carrier/boss off a GMC, they're generally an easy enough swap over and use the same honda style blades and bolts.
Thanks bigted, I had a quick look on ebay and gumtree.. nop such luck though ill keep an eye out

However, I did come across the same carrier on ebay.. looks like its a HONDA carrier that's on there.. though at $30.. yeh nah .. bit much for a cheap mower.. I might pop over to the buy/sell section and HONDA section.. see if anyone's selling..
