There are numerous threads and resources out there regarding the subject on this and other forums, so it behooves you to get knowledgeable about the process. Some vendors probably have some online videos on subject as well. Having said that:
1. You can probably borrow the video from another solid axle owner.
2. Seeing how you are going to have to remove the windshield and instrument cluster, you might as well:
A. replace windshield weatherstripping and even glass if needed. Upgrade windshield post tabs as original design sucks, breaks very easy!
B. Have gauges restored
C. Great time to rewire if you have original wiring
3. Get with SACC and/or MASACC people. There are about 80 SACC members in PA and many of these are very knowledgeable about these cars.
