MX5 Mk 3 roof repair

Hi Folks, I have had my MK3 for over three years and she has been great. However, due to lack of use recently we decided to sell it. So I booked a MOT and as I expected she walked through it with no issues. On arrival back from the MOT centre I dropped the hood but it wouldn’t go down the full way. I have never had a single problem with it until now. Can someone recommend a person would could possibly have a look and fix it. I’m in Limavady direction but I don’t mind travelling if necessary. Just a bit more awkward these days.

Many Thanks
