Blocker, chassis number on that car is actually AHZ01180M! I have the car recorded as a Sandman. Jeff, can you please confirm that the rear axle code is GU4? I have it recorded as GU4 which is not common on an L31 M21 car, normally they are GV4. The fact youhave put up GU4 also tells me it is. Would be a pig to drive with an M21 and 3.08:1 diff with ER70H14 tyres!

Just because the ID plates say Sandman, doesn't necessarily mean it still is one. The body may have been replaced with another incorrect body.
