Could anybody help me idintify the gearbox on a Vectra C elegance 1.8i?

A so called mechanic recently worked on my car and left it in a worse state than it went in. I needed a new clutch and slave cylander in it, when I got it back, only one mounting bolt was left in beth parts where the gearbox has been mounted causing the nut to snap in the top mount and the bottom mount has been cross thredded so the engine and gearboxs now rocks when i drive off (Numpty).

If anyone can help it would be much appreciated. I can be contacted by e-mail on Unsure weather a F18 gearbox is the same across the board or there is different ones for an astra/vectra ect.

Big Thank you to you all.
