Re: I'd like a GTV....
Update on the check strap!
I found that the lower bolt has come undone and is not able to locate in what I think must be a simple nut that isn't captive and must have dropped inside the door.
That's too much aggro to sort right now so it can wait until I replace me door speakers!
I removed the loose bolt and the clonking noise has gone but the door swings shut now on it's own - no big deal really and is kinda handy!
The check strap does still limit the full opening of the door so no damage will occur. I'll sort it in the fullness of time but there's no real urgency.
