Thanks to all of the suggestions about making my power operated door openers work on my shaved '38 Ford pickup. The general consensus was to get much larger solenoids or bear claw latches (becauase at present the present 30 lb. solenoids can't pull the latch lever). Another gent suggested changing out the door latch spring for a less strong one. So, I called Drake and Mac's and neither knew whether the different colored springs were of less strength. So,

-does anyone know if certain springs are less strong, or... as another has suggested,

-could I heat up my original springs and cool them slowly to reduce their strength?

So much I don't know.....

Thanks, Dr. Dave
