to make it easier to understand.

all bolt heads are to be facing the rear of the car - this is the only way you are ever going to be able to use tools on them and the nuts on the transmission side.

the disc metal inserts have projecting metal bosses, make sure those bosses go into the "pockets" in the drive flanges - either on the trans yoke or on the driveshaft.

the washers are placed where the bolt head or nut directly contacts the rubber flex disc metal insert meaning that 3 washers are used under the bolt heads and 3 are used under the nuts. It will be a sort of wrestling match because the nuts provided with the kit are locking type, meaning that the last thread in the nut is oval shaped which causes it to lock onto the bolt threads.

put some axle grease in the little centering bush on the driveshaft as the original must be dried out and useless (best if you can somehow clean the old stuff - quite hard to do honestly - but grease is required)
