i was taking off my front arb yesterday and 2 of the captive nuts inside the front legs started turning.im going to have to get in there with a hacksaw to get it off,question is how do i get in there to weld in 2 new nuts,there is a hole higher up i could maybe drop a nut in on a magnet and try and weld it from the outside.failing that im going to have to cut open the legs to get at the bits i need to fix,and i would rather not do that.cheers,lee
