      1967 Nova LS3 upper radiator hose

      I was wondering if anyone can help me finding an upper radiator hose. I have a 1967 Nova with an LS3 crate motor, a TCI pro-touring front end, and an Auto Rad radiator. I've tried matching it at 3 local parts stores, tried finding in the Gates hose guide, and even wrote TCI to see if they might know. The number on the hose is only a manufacturing number and was no help. The overall length is ~ 18 inches with 1.25 and 1.5 inch hose fitting sizes. Any help would be greatly appreciated!

      So I know you have AC but the local Oreilly's let's me roam around the back store to figure out the hoses I need. Typically I have to trim to fit.

      I've checked doing that at 3 different stores and none had anything close. I bought one hose from rockauto that was mentioned on a Nova forum, but that didn't work either. It's kind of a unique hose where it's not just an S bend, but also curves down. I'll keep checking around.

      Looking at that picture, is there an upward turn to get past the air conditioner compressor or is it a straigtht shot over it? I can't tell from that angle. My Duck Fu found these two links, the top one looks like a straight shot, the second looks like the hose has an upward turn.

      I used Dayco's website Dimensional Lookup that enabled me to post in the dimensions of both ends and the trunk length. When you punch in the numbers it will list the possibilities with pictures of the hoses that meet the size criteria that you list. Sometimes you can adjust the numbers slightly to find more options.

      Could it possibly be a custom job? I ran across this video a while back and want to try it.

      Thanks to everyone for the help. I used the Dayco site, and I think I might have found a match. I'll order it and report back. The hose is for a 2007 Toyota Sienna.

      Thanks @slazisme, I was able to use the hose I found on the Dayco website. I went down to my local O'Reilly's, and they were able to cross-reference it with a Gates 23284, and I had the hose in a couple of hours.

      For anyone in a similar situation, the hose is a lower radiator hose for a 2007-2010 Toyota Sienna and is either a Dayco 72469 or Gates 23284.

      It wasn't an exact fit, but it was pretty close. I had to trim about an inch from each end to make it fit.

      The hose fit pretty well, with the only issue being the tight turn as it enters the radiator. I'm not too worried, hopefully it will relax a bit with some heat and pressure cycles.

      One thing that was better about this hose was that there was more clearance between the hose and the A/C belt.
