And now flag pole on my new old Pajero (2011)!
Undo the spare wheel cover bolts from inside.
Open the cover.
Get two 3mm steel plates, 25mm x 50mm, drill a hole and weld them to the marter metal frame (better welding than the one I got should be easy to achieve!).
Buy two plastic electric cable shrink mounts and install them in the holes (the ones with rubber oring and shrinking nut, 8mm diam, same as my flag pole).
Close the cover, bolt it back on and you are ready to go!
When needed, just stick the flag pole in, tighten the plastic nut compressing the rubber ring and the pole would not move a mm! You have access to the nuts from top and bottom of spare wheel carter, non need to open it every time (orange gas rubber pipe is to prevent the pole from hitting the carter).
Micrometric precision 😜 and all for 30 AED, quite happy about how the all lot came together!
