who makes these roller rockers?

[mopowers]

I'd call Harland Sharp and ask them to identify them.

those are harland sharp rockers and shafts, they do not come with hold downs, and they do not have the ratio stamped on, the picture has the ratios printed on. man U scored a deal. so they have been run and have a typical raised edge at the keeper groove, take it down with a fine file or sanpaper

Thanks Marco.

Is there a way to visually tell the difference between 7 Deg keepers and 10 Deg keepers?
