So......
bought the bits from Redline - ordered Friday, arrived Saturday morning
Started to remove wishbone - ok until trying to get the bottom damper bolt out - the hex bolt has a bit of sheared off Allen key stuck in it - some one in the past has obviously either over tightened when assembling, or failed to get a very tight bolt out. ☹️
I guess I will have to remove the damper with the wishbone to try to get the bit of Allen key out.
