Saab 900 Classic Convertible ISOFIX child seat

[goodwoodweirdo]

Good morning chaps,
I've just picked up a 92 Saab 900 convertible, this will be the back up family car and to make life a little easier would love to fit a ISOFIX bracket into the back seat... I've seen lots of generic retro fit kits for 4x4's etc but nothing on the 900, I understand the 96 MY was fitted with ISOFIX - has anyone been down this route, it looks like a simple frame where the child seat base clicks into...

any pointers very welcome

or I'll need find a late 900 breaker...

cheers
Matt
