Well the saga continues, it appears that Raybestos no longer mages the WK37 kit, and no suppliers have them remaining in stock.  I did find a equivalent made by Centeric, 144.80009, but it seems that they are or have stopped production as well.  Does anybody know of a suitable replacement for the old GM# 5450435, Raybestos WK37 or the Centric 144.80009.  A brake wheel cylinder rebuild kit 1 1/2" bore with cups, pistons and a spring?
