If they are the "Rumblers" which end about under the rear axle then look for I think 2 or maybe 3 small holes a couple of inches in from the end where the baffles were riveted in place. I have a set on my bike so if you have any questions let me know

Thanks Al. I'm assuming that the cone shaped end goes in first and the square cut end is in the back, and I need to drill through the flange on the square cut end and use pop rivets to attach to the exhaust. Is this correct?
