Vin Plate for IVA

[SeriesLandy]

This evening I made my VIN plate after recieving my number from the DVLA.
I intend to weld this to the chassis.

Section 18 Statutory Plates:

12.The characters used for the VIN stamped into the chassis, frame or other similar structure must be at least 7mm high. This does not apply in the case of a "Visible VIN" provided on a Mass Produced vehicle

I used a centre punch to etch the characters, is this ok?

5.The Stamped in VIN must be marked on the chassis, frame or other similar structure on the right hand side of the vehicle. (see note 5 & 6)

I'm assuming this is the off side?

6.The Stamped in VIN must be placed in a clearly visible and accessible position by a method such as hammering or stamping so that it can not be obliterated or deteriorate.

I was going to weld my plate onto the top of the diagonal rail in the chassis bay, is this acceptable or not? Pretty much anywhere it is put it can be tampered with a hammer.
