Have been plugging away slowly now there is more light in the evenings.
Trial fitted a block with the celica box, injection and turbo setup.
Celica box required the original mounts to be cut of the tunnel, the gearstick hole moved forward slightly, and yes, a lot of massaging with a FBH however after 4 trial fittings, it now fits with clearance.
Also welded the front section on and have fitted one side of the fiberglass guards. My bet is manufacturing tolerences of Escorts 30+yrs ago were a bit sloppy to say the least. [8~2] What a horrid job.
Front section welded in place.

Passenger side twink guard midway through fitment.

How the motor sits. Is a little high, will need to slot the mounts slightly.

Should be enough room for a decent radius on the dump pipe.
