header-midpipe bolt size

[bigsparky]

I'm in the middle of an H-pipe install and I can't seem to find the right size for the bolts that join the header to the h-pipe. Does anyone know?? Please help

well i read on one or two threads that it's possibly 15mm... so I went out and tried but it won't fit over the nuts. I also tried 5/8 and it was very close but a bit too big.. what do I do??

Sorry... I meant to say that I'm removing the old one... and i need to know the factory size of the nuts..... Sorry for the confusion

whenever u take them off take them to the store and match them up... thats the best way
