After getting messed around by a few companies (amayama, pfkling, fitinparts) who all claimed to have stock of the tie rod ends 53550-SS0-R01 (a suggested alternative to 53550-SS0-J61), and took my money and then refunded days later, I picked up the vectra tie rod end 93186321 (123spareparts.co.uk), and had that fitted along with the rack arm 53020-ss0-000 which I got thanks to vanzep. So far I've not had any issues and the chap that fitted it said it'd be fine.
I also found that moog have a page on their website where you can enter the specifications of the tie rod end you need and they will suggest something that fits - https://www.moog-suspension-parts.com/u ... d_ends.asp I thought this might be useful if the vectra one’s become difficult to find.
