I've replaced the rod end bushing and still need to bore and hone them to size so I thought I might as well maker sure the C/L distance is right.
Rough measuring it looks to be a little under 7". Who knows if these rod have been resized at some point.
Mr. AI doesn't seem to know....gave me two numbers which were both wrong. | | |
