my case wasnt so bad,
Luckily the top Bolt was Snapped, wasnt the stud,
and it could easily be acess from the top.
Me and my friend, we got a welder, tick welded it and after few tried, it come loose, and sweet, didnt screwed up the thread either.
So i went to replaced them with all new High tensile Bolts and Nuts,
it is fixed now,
was plan to bring it to Liver Exhaust but i think gona charge me heaps,
My problem fixed all in 2 hrs of works, and cost 25 bucks for new bolts and RVT BLUE!
am happy!!! thanks god.!!!
