Exhaust silencer

[kev706]

Time to replace the silencer on my early 19DG. On looking at the nuts that need to be removed they look like rusted scabs, if there to far gone for a socket whats the best way to remove them. Thanks.

Chop them off with a grinder then drill out the holes and pop an M8 nut and bolt through.

drill 3mm hole into what is left of the flat of the nut to about .25 of the stud diameter, use larger drill to drill away side of nut, split with a chisel and peel away remains of nut,'simples'
