10" drum or Kelsey-Hayes

cylinders are EZ to repair, just a $8 honer and some $1.50 seals. Or ridiculously cheap 4.83 remans from Rockauto.http://www.rockauto.com/catalog/moreinfo.php?pk=966851 The Calipers are about 50 a pop with 53 core charge so not bad if you can cobble your cores back to shape.
