1934 ford shock arm

[Brewsterbuff]

I have a set of M & S Hydraulics shocks on my 1934 Brewster Town Car. The arm has fallen off of a front shock. Can any one tell me at what position I should replace it? My assumption would be at mid travel on the shock. Does that make good sense? It appears that M & S is no longer in business. This arm is just a press fit so I plan to press it back on using LocTight, in case the press fit is not quite snug enough. Thanks, Don
