Brake Drum 9 Inch Standard Rear Triumph Austin MG Riley Morris Reliant Scimitar TVR  210578
Brake Drum 9 inch - Standard - Each - 210578
These brake drums have a central hole with a standard size of 70.5mm for them to fit numerous models across the Triumph range.
If the hole is too large for your Triumph model, any potential spigot-ting effect will be neutralized by the tightening of the locating screws.
The stud holes are drilled to a PCD of 114.3mm (as original) and are suitable for fitting with standard pull through 7/16 inch studs as used on all but early Girling axled cars.
The hubs on Girling axles are fitted with screw in, front mounted studs.
These studs, which feature a slight shoulder, may not allow the drum to sit flat on the hub. This can be resolved by drilling the hub and effectively converting it to use the later pull through studs.
The Locating Screw Holes are drilled on a PCD of 100mm (as original).
