There are some fitting issues with the pillars but mine has been fine. For the gauges your better doing a search as they can be quite fiddly especially routing pipework through to the engine bay
When fitting the pillar, degrease the bare paintwork so that the velcro gets a good stick. If you dont have a general degreaser, some alcohol (vodka) will do the trick. The velcro should then stick nicely onto the paintwork!
This is the reason some people struggle with them fitting nicely with the velcro detatching itself
