I am looking to put a new fan belt on my 68 road runner, and would like it to look as OE as possible. I'm trying to find the correct part number for the fan belt for a 68 road runner with a 383 and no air conditioning or power steering. The two part numbers I keep coming across are 2806216 and 2843221. I think either would fit, but I would like to get the one that is most correct. Thanks in advance for your help and suggestions!!
