where to get chr_rpts file for dbSNP human 36.3 assembly

Dear list,

In terms of dbSNP database in NCBI, I can get the chr_rpts files for
the most recent 37.3 assembly from the following FTP site,

ftp://ftp.ncbi.nih.gov/snp/organisms/human_9606/chr_rpts/

My question is how/where I can get these chr_rpts files based on the
36.3 assembly

Thanks,
Shirley
