Iron Rocker spacers Early 273 mech type

OK I have a complete set of the older 273 mech adjustable rockers. I am just going to put new lockable set screws kit and 2 new chrome hardend shafts on them. I have a new bolt hold down kit and I have the shim kit that has sizes from .005-.015 for centering rockers.

But does anyone have a set for sale or know where I can get the 1/4 wide spacers that these old style rockers use. They go in between every rocker. I would like to buy a new kit of 8 of these 1/4" wide spacers for these shaft rockers. :supz:

The rockers are set up in the following patterns
