I removed the roof rails off my 260RS today, looks heaps better.
tools needed are:
Small flat head screw driver
phillips screw driver
12mm long socket (preferrably 1/4 inch drive)
14mm spanner
1/4 inch drive rachet & extensions
Gentle hands
remove the rear section of the hood lining then just let the front section drop down. u only need enough room to squeeze ur 12mm socket & extensions up to undo the nuts that hold the rails on. there are 10 all up. u'll need the long socket for the 4 at the rear.
once all the nuts are undone, pull the rails off, they may need a little assistance as the have been on there a long time.
now that the rails are off u'll be left with 6 rectangular holes in the panels which will need to be filled ( will update this when i have done it.)
u also have 10 holes in the roof which will need blocking off so ur roof don't leak! I'm planning on using some stainless cap head bolts and washers and some rubber washers as well as a bit of sikaflex just to make shure.
will post more pics and update topic when i have finished it, public holiday so bolt shop is closed today.
