Can anyone = tell me the size & length of the bolts that bolt the catalytic converter to the crossover at the "J"? I think they are M8 x 1.25 but not sure or = of the length. I do not have the bus today so I am not able to measure them. I am replacing the muffler & tailpipe this = afternoon. I am also going to remove the converter & make sure it is OK. = I would like to get the hardware on the way home. Thanks.
