I JUST GOT THIS INFORMATION FROM A CORVETTE OWNER. I am unable to verify it. Please help me if you can. From:igaston To:mikes_garage_sale Sent:Dec-12-19 22:55 New message from: igaston (937) Hey Mike, My research indicates they are correct for top radiator hose on early-57 to mid-59 Corvette, 2 each. I imagine they are correct for various 50's chevy v8 small block too with 1 7/8" radiator hose, but not sure. I think the GM part is #443634 but can't find it on web, just the corvette assembly manuals for 57/59 I have.
