Hi John,
If you are in the UK contact BSK, Metropolitan or Undyarncrafts; they may be able to help you. They all have web pages with contact details.
Some Singer machines were made by Knitmaster/Silver Reed so it may be possible to use that make of needles and needle bar. If you have the old bar, you can replace the foam with self adhesive draught excluder making sure to tape the ends securely.
Hope this helps,
