Top A arm shock mount shell location on chassis needed .

[Redsat]

Long story but my 65 Satellite now has a new sheet metal front end and chassis rails from the firewall forward non of it standard . What I want is the measurement from the front K member bolt mount to the first edge of the shock shell ( the bit thats welded to the inner guard) so I can replace them.
In Millimeters please .
Thanks in advanced .
