71 Servi Siren

[gcooperlll]

Trying to get the front siren on the servi functional - model 58 with foot control. DPO hacked up the pedal to run a late model clutch cable to activate siren. I can get a new cable made but I don't have the dimensions - length, cable diameter (housing and inner) and end nub sizes. Also need a pic of the pedal displaying how the cable end attaches. If anyone has a stock setup and could provide the info I'd be most grateful. Could also use a description of cable routing.

Thanks Cooper
