Many thanks to dfcas (Dan), as he sent me a few spacers and after a bit of work I got them to fit!
At first the spacers would not fit over my BB cup threads. Since my BB is Italian threaded it's O.D. is 36mm and the spacers I.D. was 35mm. So after reading a few more post on other forums I took a half-round file to the inside of the spacers to widen the I.D. to 36mm. Worked like a charm.
I had played around with the idea of making a cut in the spacer so that I could spread it to fit, but filing the spacer worked.
I used a single 2mm spacer and it was just enough to keep the chain ring from rubbing.
