Thank you Warren and John.
I have just now worked out how to move the roof in and out without changing the cable anchor point a couple of times each way ...important as next step is to control the roof from my van.
I think I can do without the new runners that I ordered so I am going to see I they will let me out of the sale and see my new astro friend and see if she would like to capture Andromeda

plus buy a double garage for the car and me

...how they treat me will tell if they get any new business..I would buy a garage in a heart beat but dealing with council puts me off..I will see if they will do that then great..
I gave them a $150 deposit so even if I drop that no worries.as hard as that is to take I won't have to pay the balance or sort out delivery..I should not have been so hasty ..I am going to just replace the wheels that are there with decent ones and I can't see that not working.. I have worked out I only need to Jack the roof a couple of mm and remove and replace wheels by rolling them on the inside..changes everything...
I can't do the winch fix today as I have no petrol for my genny ...so I am going to take a nap in case it is clear tonight..the inverter spat the dummy so I imaged using the genny last night and used all my petrol...
