As long as they plug into the connector they will work. Did you test your system with a vacuum pump?

The vacuum lines are known to get brittle with age. By all means swap the solenoids but post back with the results. FYI the GEM grounds the solenoids to activate them. The one closest to the fender engages the front axle and the one closest to the engine disengages it.

Have you thoroughly checked the vacuum solenoids on the firewall and the vacuum lines again? Even the smallest crack will cause you to loose vacuum and then it won't work.

Start over again from scratch. Does the 4x4 light come on when you switch to 4Hi? Does the Low indicator come on in 4lo?
