1968 Chevy C-10 Passenger Door Alignment Question
 

Hello, I have installed a new Spal Shaved 40 Shaved door kit in my truck. The drivers door works perfectly however the passengers door does not. The solenoid tries to pull but you have to hit the button 7-8 times. I have tried everything I can think of to loosen the latch as that is what Spal tech department says is the problem. Any Ideas. Thanks
