Kev- you didn't miss much
Pete- what's my middle name?
Thanks for the sensible advice chaps, much appreciated. Just to re-assure you- It ain't a daily driver, i'll be VERY aware of the limitations of both parking devices, no-one else will drive it and if i park it on a hill i'll use a brick
(My old AMC Javelin had a highly technical mod to the Mk1 parking brake or 'parking brick'.... the Mk2 parking brake was a brick on a rope- just open the door and reel her in

)
No-one will believe you...
