Could somebody give me a half-arsed drawing with rough dimensions of a sierra diff (and a granada diff if i'ts massively different) as I'm CADing up my roadster chassis at the moment and need to understand how much space I've got in the rear suspension frame?

Much appreciated!

Sorry I don't have a CAD drawing of the Sierra diff.
If you are worried about space then have a look at Freelander differentials - they are a loy less bulky.....

Look for a drawing called new sierra.dwg (on clubman builders resource)
It shows a Sierra based locost.
