In my case it's a kit car with big wheels that makes needs a lower ratio than I seem to be able to get in 7".
I now have a 4.27 which presumably is from a Granada.

I also now have a 7.5" beam to fit it to.

Is this a reasonably straight swap otherwise?


Main issue I can see for now is drive shafts to suit drum brakes? Any advice on that would also be useful
