Harland Sharp rocker shaft alignment

I would not use the brass sleeves. The spacers and shims are what aligns the rockers.

The bolt or stud being centered in the hole in the rocker shaft means nothing.
The concern was that the hold down for the shaft doesn't seem to center itself on the hardware, effecting the shim pack when installed. Your correct that the shaft itself is a non issue. A set of PRW rocker shaft hold downs didn't have the .400" hole for 5/16 hardware and cleared up the side to side play consistently.

Thank you for the response.
