Thanks Matt, your pictures were very helpfull.
Guess what, the gearbox mount was the correct one, I thought I had a sierra one, but it wasn't.
This is the progress I made since. (pictures are clickable)
Rear axle with brake lines

front brake lines

Throttle pedal having the good shape now (was a bitch to get right)

Trolley wheels decided to give up on the Zetec

So time to put it in

It's in
The sump is 5.5cm (+2") under the bottom of the chassis, is this good/acceptable? Also the top of the cambeltcover on the front of the engine is 53cm above the bottom chassisrail(topside) will it fit, can anyone with a zetec measure this? I'm asking this because I have no engine mounts and have to weld em up, so trying to get a good position.
The gearbox has just finger thickness clearance to the chassis, is this ok, looks like matt's picture, all pretty close.
