mapping with CB4858?

I can’t use CB4856 for mapping, and am interested in using CB4858 instead. Has anyone tried this? If so, let me know if you have a set of snip-SNPs distributed across the chromosomes (it will take me a while to go through the polymorphisms in Wormbase and find SNPs that change a restriction site).
thanks!

The CB4858 SNPs are located on dbSNP.
