Restore the stock rear look of your Thunderbird with the genuine Royal Enfield 845020 – Rear Number Plate Assembly (Milky White). This is the OE rear plate/panel listed in the Thunderbird 350/500 NTB parts group and also shown on dealer catalogs for Continental GT 535, so we are listing only these confirmed models to avoid returns. It’s the small rear number-plate panel that sits under/behind the tail-lamp bracket and aligns the registration plate, reflector and indicator spacing. Because it’s OEM, the mounting holes, bend and width match the TB/GT tail perfectly, and the factory milky white finish matches the OE scheme used on these models — no repainting or drilling.

Use this part when the old plate has cracked in a tip-over, gone yellow with age, or you’ve replaced the mudguard/tail-lamp and now want the whole rear to look factory again. This is not a universal plate; it is the RE part 845020 as shown in the TB/GT fiche, so it’s the safest option for underthehood.co.in to list as “direct fit”.

FAQs

Q1. Is this metal or plastic?
It is the OE rear number-plate assembly/panel supplied by RE for TB/GT — the same style you see in the parts book, not a universal aftermarket plate.

Q2. Will it fit Thunderbird X (TBX)?
No, TBX uses a different, black rear assembly. Keep 845020 for NTB Thunderbird 350/500 and GT 535 only.

Q3. My old one is yellowed — is this actually milky white?
Yes, this is supplied in milky white as per the original description, so it refreshes the tail without repainting.

Q4. Does it come with bolts?
Usually panel only. Reuse OE M6 fasteners from the TB/GT tail section or add them separately.

Q5. Can I drill extra holes for a different plate size?
You can, but drilling voids the “direct fit” advantage.
