Serpentine Rad hose Please help ASAP

[jasonrog]

I am running a serpentine system from a 1990 chevy 1/2 ton V8 in my 71. I blew my top rad hose today and do not know what application of hose I need. The hose I was using, I found in the wrecking yard. I do not know what it was from. The hose I had fit a little too close to the alternator, rubbed, and began to leak. The alt. is in the path of the 71 stock hose, so I need something that will go around the alt. I looked at a hose for a 1990 1/2 V8, but the angles didn't look right in the parts store. One of the fancy chromed flex hoses isn't an option either. Price and availability issues. I need my truck running tomorow afternoon. Please help.
Thanks
Jason
