i bought mine on ebay. you can find them online at a few different sites. the only bad i found is that the info on the plastic one says that you shouldn't tighten the clamps to tight and should then wire the two hose clamps together to keep them from blowing off, i bought the brass one so it should be able to be tighten up without worrying about cracking it.

 

save your self the bucks and go to target buy a 9" spagetti strainer ( 8 Bucks ) cut out the wire and wrap around a 3/4 " dowel,, have a sharpie handy for marking purposes,,,, pull upper radiator hose and stuff dowel'mesh into the inlet tube and " wiggle" around to expand the openings,,,,,,,,,while it's in ( all the way to the front of the tank) mark with sharpie and then when you pull it out leave approx a 1 1/2 " and cut off the rest,,,, on the material that is folded ove in order to get it in try to make it only 1 fold over and cut off all except approx 1 " and make sure that ,,that side faces the "
dead end of the water flow of the upper tank" when your done triming everything stuff it in the radiator tube and fold the excess over the tube and the slde the hose over and clamp it down,,,,it'll catch the crude and still let the flow go thru to keep the engine cool,,,AND it was said before,,,, if you need it for more then a month or 2 you got some problems happening..... and yes it's true it does look like a medieval condom but it works
