No worries on the front bumper, you can take the engine out if you need to without removing the bumper. No need for that if your just doing the bearing/release fork thou-
driveshafts out,
flywheel cover plate and front engine steady off,
gear selecter bar off (undo the nut on the gearbox stud (rear) next to the starter motor while your under the car),
unbolt the block to box brace from the gearbox,
starter motor off,
take the weight of the block with a jack on the sump plug area,
gearbox mount to front of subfame off,
remove the nut, washer and plate on the gearbox to bulkhead mount,
remove the 4 long bolts and other stud nut (front of box) that hold the box to the block,
jack the engine up a touch until the gearbox bracket moves off the bulkhead engine mount stud (in other words take the weight off of the bracket)
remove the gearbox bracket,
slide the box back, it's heavy!!
For a bit more room drop the rear nearside subframe bolt out and bar the subframe down 3 inch (wedge a 30mm socket in between the subframe and chassis) . When i changed my clutch i left the box in, just pushed it back between the inner wing and subframe, i had loads of room to work-
