Maybe but unlikely, the car is 25 years old so someone could've changed them over during that time. Never seen or heard of that being available from the factory. how long have you owned it?
since november. Its got receipts right back to original bill of sale. it could well have been changed along the line just wondered if there were any other early saffs with the boost gauge.
I may change them back to original then as thats the route im going down with the whole car.
