Before I dig myself into a hole, thought I better ask for some advice/tips here. My 1981 T3 California came to me with a crack in the plastic gauge housing. It is totally an aesthetic issue as everything works fine but a replacement popped up online at a price I couldn't refuse. Here's the "new" one:

I removed the two screws holding the part in question to the other part housing the gauges and began to gently pull up on the part I was trying (hoping?) to remove. Then I tried not so gently. Then I took some photos and stopped to start this thread.... The "problem" appears to be that all the bulbs invoked are inserted into recesses on the underside of the part I'm trying to remove:

I can separate the two parts just enough to see in and see a mass of 40+ year old wiring and don't know how hard I should be pulling on things....
Is there a trick I'm missing?
In the good news department, while doing all this, I took the opportunity to remove the speedo so I could get a close look at the missing trip meter reset knob. Yay! It wasn't broken off, just not there and the threads look OK:
