Bill,
In a nutshell,
1. the differential has to be flipped over so you don't have 5 reverse speeds. The ring gear bolts should be safety wired while everything is apart. You can buy bolts with the holes already in the heads
2. The inside of the case needs to be machined so the ring gear bolts will clear without hitting.
3.The gear cluster assy has to be pulled out so new drain and fill plug holes can be drilled and tapped into the case.
4.Several small holes need to be drilled in the webbing between the transmission and differential cavities so oil can flow between the two.
5. A vent needs to be put in the cover (which was the sump on a Pantera) or you can buy a new cover from Lloyd with the breather already installed.
6. I also put new oil holes in the differential side plates so the carrier bearings can get plenty of oil. (The existing holes are on the bottom once the box is flipped)
7. You need a ZF maintenance book and some specialized tools to work on these boxes. The differential can't be removed from the housing without pulling the inner races first. Special puller needed. I spent 2 weeks just making pullers, mandrels, etc.
I have some pictures I can post if you're interested.
No dry sump. I modified the stock pan...cut out the bottom and put on a modified sump, windage tray, pump pickup, etc. Pics of it also if interested. Off the top of my head, ERA's spec is 7.25" or 7.5" max below the block pan rails. The chassis has some of the same cutouts that they use when putting a big block in. ERA has my engine/transaxle so they can trial fit it to make sure everything clears.
