Swap new (style) handlebars for old?

[swee'pea99]

I got some handlebars off ebay without realising that some have fat bits in the middle and others don't. The ones I've got are like this, and the ones I need are like this. Anyone up for a swap?

i've got some a bit like you need but i've got a vague feeling they are less than 26.0mm, which i'm guessing is what you need. although if you think they might do or you can get a shim pm me.

Thanks bonj, much appreciated. I'll get back to you soon.

Hi Bonj's turned out to be steel - I should have said, I'm looking for some reasonably light ones - anyone?
