All, lots of detail if I was looking at car but having a remote non car person have a look becomes more difficult.

I'm still having thoughts of turning one of my R129 SL's into an AWD car. One of them is going to be turned into a track day car and AWD would make it more interesting. It isn't a question of if I can do it ( I can ) it is a question if the added weight and seemingly somewhat fragile front diff would be worth it.

Transfer case selection is the next sticking point, I'd have to decide on open center diff, viscous coupling , some sort of electrical variable locking.
