Desperately need some help.
Trying to remove Steering Column from spitfire 1500 (to replace upper and lower bushes). Am clear on procedure (via Workshop manual/Haynes Manual) but for the love of me I just cannot determine how to remove the Upper Column Clamp Bolts (UKC 7070).The workshop manual refers to cap screws, they look as if they are but with the "allen key centre" " filled in " !! See attached photo. So, no means to use allen key, spanner or whatever
Would really appreciate some help on this ie how do I unscrew these ??
many thanks
