my machine shop forgot to mark the main caps befor ethey took them off, they have arrows and numbers which i know the arrows goto the front but do any of oyu know which number on the cap goes in which postion? here are the numbers my shop did the same thing , here are the numbers on the top of the caps
20, 43, 63, 83,

 

Unless you are talking about some other block, the lt1 blocks have the position and arrow cast into the cap, no need to stamp them.

 

Yeah just look harder!
