maybe I've phrased the subject matter wrong.
on standard vehicles the chassis number is on the VIN plate and also hidden for security reasons generally on the drivers side inner side. but what is the legal requirement for the SVA can I put the chassis number on a plate and then tack weld it on or does the chassis have to be permanently marked

tony

Welding a plate onto the chassis is acceptable (at least it was at Gillingham last month) but I was advised to put it in two or three places around your vehicle

I welded a plate on as well. I also put an ali plate on the scuttle.

stamped numbers on an MK chassis one, it dented the tube...so I'd use a welded on plate.

Hi Tony

For SVA they only want to be able to check the I.D they weren't interested in whether is was permenant.

He looked at the visible plate on the battery tray and didn't ask about the chassis being stamped. It's DVLA who need the chassis to be stamped.

It might be wise ringing the test centre you intend to use as it could be one of those things that varies from test centre to centre.

Cheers
Nigel

Dented yours cos you're a CEC guy and not a BEC guy.

Tony fogot to mention, you can stamp the chassis rail without denting it. I clamped some angled ali to the side of the rail and used it as a guide to ensure that all the letters were in line.

This also means that the numbers are well towards the endge of the rail and unless you really go to town with a hammer it shouldn't dent. i just used one clean reasonable power blow with a small lump hammer and it worked at treat. Then rub some contrasting colour paint to your chassis into the stamps and wipe the excess away and then it stands out much clearer

Hope that helps

if doing this on a Westfield the chassis might shatter, use a permanent marker instead

Stamped mine onto the ali cover over the pedal box and onto the ali floor panel in frontof the drivers saet. No problems.

As a retired Police Officer who did forensic tests on burned out stolen vehicles the reason for hidden VIN numbers is to identify the vehicle. Stamped and welded plates should be fine. The problem of VIN numbers on aluminum is they tend to melt leaving no record of the vehicle. If they can't identify your stolen car, the insurance may not pay.

SVA and DVLA wre happy with a rivvetted alloy plate.
Then stamp more at leisure
