Pleased to say I finished all the reassembly work last week and the car passed its MOT on Thursday with a clean sheet. I have quite a long list of things to finish, like fitting the radio cassette and sorting out interior trim and drivers' seat height adjuster that seems to be jammed. Will also get alloy wheels refurbed and clean up the engine bay properly. BUT the important thing is a mk1 Tipo is back on the road and running really well. My wife will be using it as her regular driver and she is delighted with it.
Yes Bluejohn, I do have a sunroof (electric). Took a bit of effort to get it to work , I suspect though lack of use, but now OK and no leaks so far. Would love to join a local meet sometime later in the year if others are interested.
