Here are some photos that may help:
Fixing straps over the tank.
Position of the holding bolts at the rear of the tank (below rear window).
Position of the rubber buffer pads that the tank sits on. These are the 2 rear ones, and there are 2 more at the front as in Peter’s photo.
Rubber buffer pad location and spare wheel position.
New buffer pads (I gluded these down) and used a felt faced cover to sit the tank on.
The tank straps are in 4 pieces - fixed over the tank towards each end, and each long and short section is joined by a fixing bolt once the strap is located over the tank (see above photo).
Again I used felt covering on the sides that are in contact with the tank (I didn’t want to scratch my new paint work !!!).
