WTB - 3sgte gen II valve lifters/buckets

Hi,
I found that three of the valve buckets/lifters in an engine I'm rebuilding had corrosion on the top edge (left too long in wreckers yard) and I want to replace them.
 
Anyone have some buckets for sale or can suggest to me where I might get some.  I'd prefer Aus as I'm now stuck in my rebuild.  I'd bought a set of V6 lifters which look great and fit beautifully however the shim to valve tip web of the V6 buckets is about 0.18mm thinner than the 3SGTE buckets so I'm then up for replacing all the shims and I'm not sure about fitting such thicker shims.
 
My buckets are the gen II shim-over-bucket design.
Thanks
Brian
