Both of those tools will no doubt work. I didn't think about using the rocker shaft with a tool like in the pictures. (I guess it is reluctance to disassemble my rocker shaft). I knew I would get the answer here on the forum. Thanks Charrlie, ch1II and 1WildRT.

I have so much "stuff", I just took an old shaft and rocker arms, and cut the shaft to straddle two stands. Then did some cutting and grinding on the arms to get the correct seperation.
