1. Has anyone replaced their original glow plug relay with the newer style sold on Fastlane? At the relatively small cost ($60.00) it seems like a good investment since I live where it freezes about 5 months of the year. Does it improve non block heater starts?

2. My foot flap actuator (center just behind the radio) seems to have a failed diaphragm. Can you order just the diaphragm or can I use an actuator out of a 123? I checked the part numbers and they are different but perhaps I could just use the diaphragm out of a 123 actuator? How hard are these to replace and does the top just pop off the actuator so you can access the diaphragm? Never done this and there are no instructions anywhere that I can find.

Thanks in advance...
