Cobras came first.
The bracket (Cobra unique supplied by AC Cars), spring tab (fabricated in house by Shelby American), the chrome plated push rod (a Girling supplied part with its end cut off and rounded for a Triumph something), ball nut (Cobra unique), and spring are Cobra specific parts. The Girling supplied (complete with unified threads identification) jam nuts is just a Girling sundries type piece.
The Sunbeam Tiger bracket is not as strong as the one for a Cobra. The ones I have held are not as thick in cross section (significantly thinner with the long bolt shorter than the corresponding one in a Cobra) where the bolts fix it to the engine and the webbing is not exactly the same. The Cobra part is identified with the same foundry logo as the late Cobra alternator bracket which was also provided to Shelby American by AC Cars. Both the Cobra and Tiger brackets are cast steel.
The ball nut for a Tiger does the same job as the one on a Cobra but that is just about where the similarities end. Cobras use an extension type coil spring between the end of the clutch fork and a fabricated (from wrought black angle iron) tab fixed in place by one of the bolts securing the slave cylinder to the bracket. Tigers used a custom spring clip to hold their push rod ball nuts to the fork.
All the Cobra and Tiger pieces have been copied and sold commercially at one time or another; and get mixed in the secondary markets.
