What is the gross vehicle weight of a 1999 vw t4?

My 1999 Multivan is plated at 2600kg (2.6 tonnes). I believe standard panel van T4 is plated at 2515kg (2.515 tonnes/ 2.47 tons). In any case, they're all over the 2.5 tonnes restriction for "larger vans" & "motor caravans" for the new Low Emission Zone (LEZ) rules from January, though you can get them downrated to 2.45t & re-plated, then apply to VOSA for new log book for around £120 + the cost of a VOSA weighbridge cert (£12-30) then registeredwith tfl for the new lowered & exempt weight. Cheaper than going into the zone & paying the £100 charge on 2 days !
