Evolution of Ford Uprights.
Far left is a Scorpio Cosworth, centre is Mk 3 Granada knuckle and on the right is the standard Sierra upright. The plan is to try and use the Granada knuckles if the Scorpio hubs will fit. The advantage is that they are a bit more substantial and have 12mm bolt holes for the calipers which means I can use bigger brake discs and calipers. This is a bit of a side trial which has someway to go before I can be sure they will fit and not screw up the geometry, etc.
