The MGF and MG TF drop glasses are tinted as standard, no clear-glass option is catalogued because tinted glass was fitted from factory on all variants. The LH and RH glasses are handed (different part numbers) due to the curve of the cheater seal at the front edge of each glass. Each drop glass attaches to the window regulator via four screws through the glass itself, with two shouldered retaining bolts also catalogued. The window repair rivet on the live page is a common ownership item: the regulator cable's plastic clip that attaches to the glass eventually fatigues and breaks, dropping the glass into the door and requiring either a new regulator or (more economically) the repair rivet plus a small reattachment.
The repair rivet is a well-established MGF fix.
Window Regulator, Production Change at WD030082
The window regulator is a cable-operated mechanism driven by an electric motor in the door, raising and lowering the drop glass. The regulator was redesigned very early in MGF production at VIN WD030082, a production change that suggests a reliability issue with the original specification. MGFs up to WD030081 use one handed LH/RH pair; MGFs from WD030082 through all MG TF production use a different handed pair. Ordering the correct regulator requires knowing the MGF's VIN for pre-Mk2 cars; MG TF owners can order directly on model.
A slow or noisy window is typically dry or worn channel runners (a channel lubricant will often restore smooth operation), while a window that drops into the door and won't raise usually indicates the regulator cable clip has failed, addressed either with a new regulator or with the window repair rivet solution above.
Drop Glass Stops, Rear Guide and Related Adjusters
The drop glass stops set the lower limit of the glass's travel, catalogued in pre-WD037077 and post-WD037078 MGF specifications. The post-WD037078 stop is shared with all MG TF. Fixing screws for the stop changed at the same VIN breakpoint. The rear guide assembly, handed LH and RH, guides the rear edge of the drop glass as it moves up and down.
The guide assembly includes its sleeve, bracket, and originally a screw/washer assembly. At MG TF VIN 3D618503/3D618504, this screw/washer assembly was replaced with a separate screw and separate washer, and the catalogue explicitly notes the later separate-component specification can be used to retrofit earlier cars, useful when the original screw/washer assembly has fatigued.
Cheater and Seal Assembly, Integrated Front Seal
The cheater and seal assembly sits at the front edge of the door where the drop glass meets the door frame, providing the weather seal along that edge. The LH and RH handed cheater assemblies each include the front drop glass seal as an integral part, the seal cannot be ordered separately, replacement requires the complete cheater assembly. Mounting fixings include four screws per side and two clips that secure the cheater to the body, with the clip design changed at MGF VIN XD507676/XD507677, the earlier plastic clip was replaced by a revised version that carried through to MG TF.
When replacing cheaters as part of a regulator or glass service, the later clips are the current spec and will fit earlier cars.
