The TR4/4A Rear Wings (850475 Left Hand and 850476 Right Hand) and TR250/5 Rear Wings (811989 Left Hand and 811990 Right Hand) also have mainly fast assembly Acme threads.
All our fitting kits come with a list of contents and an excellent pictorial representation of where the fittings are placed and how they are assembled.
The rear wing to ‘B’ post fittings use an HU706P, which has a pointed head screw and the pointed head was fitted to all these cars originally. The pointed head enables faster assembly.
The Acme thread bolts in the Rear Fitting Kit (OE number UL2705) are a 1/4 Acme thread and 5/8th of an inch long.
All components in both of these kit are made in England
