Plenty of big jobs on the back as well. The one you may need some help on is fitting the differential, my wife helped out there.
Start off with tidying the transmission tunnel up following the engine install. Once done time get the differential into place before deviating from the build manual and fitting the roll over bar. Make sure you fit the shoulder harnesses before the roll over bar!
Once done you can build up the back end, tube and dampers, radius arms and a-frame, driveshafts and anti roll bar, before finally building the rear hubs, which is one of the last major jobs you will do on the car!
Getting there!
