Anyone know what size the nuts are; which are welded to the iron straps, on the Stan's 89-93 exhaust muffler? I just finished up fitting up the Stan's exhaust (turbo back) on my 93, and need to connect my muffler straps to the exhaust. I need to know the size of the nuts on the muffler, so I can get some gr 8 bolts at the hardware store, to connect my straps. Any help is appreciated!
