Don't know at the moment. However, it's a 1968 model year-released part number. Of course, it could also have been used for later years. The trouble is I don't recall any 1968 or later application that used the same hose for both sides.

Hi Ralph,
I was going to ask you to re- check the numbers. The 3932476 GM RC is correct for the driver's side of our 73. I believe it is also correct for 69-74 small blocks too. The passenger side would have 3947740 on it. Like Joe mentioned above, I don't think the hoses were the same on both sides.
BTW, What is the number stamped on the flat surface on the diverter valve below the muffler? Is it 29199? That's what our 73's had. It's a tough one to find. And a rather costly one, as I found out to be true!
Hope this helps,
Regards,
Jimmy

My recollection is that one of the hoses is a molded hose and the other side is not a molded hose. So, there should be different part numbers for each side.
