Hi Amklyde, I don`t know what year these shafts are off,it`s a heinz 57 pan. The one end is centre drilled,which end has the pressed in plugs? I sent back 2 complete sets of blocks and shafts,one set from V-Twin, one set from Custom chrome.They were pathetic, all had between .012"-.014" end play,and excess clearance between shaft and block, they were worse than my worn out ones. I know I can repair the blocks,with out too much trouble. I know where I can get some shafts sold by Eastern,do you know if they are any good? Another question,what if you were to grind the shafts and industrial chrome them? Would the chrome stand up?Thanks.
