The cooling tubes are 1-3/8" outside diameter. The original one piece pipe measures ~61" long. The stainless two piece pipe set that I have measures 37" and 23", for a total of 60". This would leave about 1" +/- between the two pipes at the connecting hose.
If you can find someone that has a beading tool, you could have them put the beads on your tubes. As mentioned in several other posts, the hoses seem to seal just fine (and not blow off) without the bead. I have one tube in my car that doesn't have any beading. It has never given me any problems and it's been in there a very long time.
