3 different power steering belt options for 1967 Coronet 500 w/318

[tddawson]

I just bought a '67 Coronet, and the belt for the power steering pump is missing.

O'Reilly's has the following 3 options as a replacement belt for a 1967 Dodge Coronet 500, 318 w/AC:

39-1/4 Inch Belt Outside Circumference

40-1/4 Inch Belt Outside Circumference

41-3/8 Inch Belt Outside Circumference

Does anyone know what the 3 different sizes are for? Or how I might identify which one goes with my car? (short of buying all 3 and trying them all on to see which one fits "best"?) I'm not sure which pump I have, so have included a photo - if anyone can help ID it, that would be awesome!



Thanks!

I would just buy all 3 and pick the one which gives the best tension then return the others. I HATE having to make an extra trip in the middle of a job, but don't mind returning stuff afterwards when the job is complete. Those old parts books are notorious for having mistakes anyhow.

I ended up with the middle one - 40-1/4 Inch Belt Outside Circumference, There is enough tension adjustability that any of the 3 probably would have worked!
