Frank, the wheels are off the car-& I can only just open the bonnet, so no way of getting any pic's.
I quess the car had various axle types fitted?
The gear change feels like a 5 speed, as to the engine- I have a 302 Ford.
Have been hopeing to get a 944 turbo axle ( might still yet, looking at one later this week), but if useing a Audi axle may just use a Rover / Buick 215ci and use a turbo.
I think the 215 with a turbo might work well, given the softer power delivery that you get.
