[Tigers] Tiger Clutch Slave Cylinder Bracket Question

[Joel Martin]

1966 MK 1A Tiger
 
It appears since I had to change out the bell housing on a 1965 289 HP motor,
it had a bid hole in the bottom, that there must be a different clutch slave
cylinder bracket for the new 6 bolt bell housing C5AE-6015E as the 2 bolt
holes no longer line up.
 
I believe the old bell housing was a C5AA-6394-B.
 
Was there a different clutch slave cylinder bracket for the C5AE-6015E?  If
so, does anyone know the part number and\or have one they would part with or
are they still available new?
 
Many steps forward, many steps backwards.
 
Thanks
