Engine separating from gearbox!!Help!

Hi all,

Ive developed a problem, I'm no longer able to select second gear in either high or low range.

After getting under the car all 7 (or so) bolts holding the bell housing to the engine are missing!

Does anyone know what size these are? I think they might be M10 but I'm not sure on the length.

Please help. Does anyone have a photo of what these bolts look like?

Thanks in advance

Lee
