Clutch fork

[rsk289]

Well, the best laid plans...
Planned to install the engine today, but have got hung up on the clutch fork. I have an early 289 (probably Mustang) style, but it's a cheap repro and the two fork fingers don't seem to be long enough to hold the springs on the release bearing, and it binds on depression. I have the correct 'C3' 5-bolt bellhousing, and I think all the clutch hydraulics and hardware should be the same as Sunbeam Tiger (MkI, which had the 5-bolt 260). I have the correct bracket for the slave cylinder mount - I bought a new casting for this from the US, which turns out to be exactly the same as the old Tiger one I had, and the slave cylinder is a common Girling one.
What I don't have is a Tiger clutch fork! This is C3AZ-7515-A, which takes a special pushrod with a curly spring to hold it to the fork. Rod and spring I can get, but does anyone know which fork will work with this? NPD and the Mustang outlets supply a fork for 65/66 6 cyl Mustang, 37515B, which I am told should work - anybody know if it will, or of an alternative?
Real pain - I hoped to get the motor in and check those angles. There's always something you don't foresee...
