I made my number up from the cars make, build number and my birth year. Its 16 digits long. Sent it off to the local office askign if it was OK? They repliedsaying it was fine and also included all the forms I needed to register the car
I stamped the number on the alumninium plate covering the footwell and also onto the aluminium floor just in front of the drivers seat. More or less where you would find it on the donor Sierra.
No vin plate as such and stamped onto ali panels rivitted to the chassis.
No problem what so ever at SVA (Beverley)
