Correct alternator belt for 67 350?

[1967RS/SS]

Just put original iron intake and script valve covers on and the alternator belt does not fit.  The alternator hits the valve cover which doesn't allow the belt to slip over the pulleys.  That's with all the brackets loose too.  

Engine is L48 350 w/ AIR and PS and no AC

Anyone know the dimensions and/or part number I would need?  AIM shows p/n 3847708 for a V8 and Pep Boys gave me what's in their computer...

You can get belts by the inch at most auto parts. If the one you have is too short get some cord wrap around the pulleys. Measure the length of the cord, get a belt that long. Make sure it is the right width. You should be good to go. Measure carefully.

1969 Camaro Parts book -  #3847708 - 3/8" x 53 1/2"

1975 GM parts book list the number for the same specs as #9433759.  This number may be replaced as of today, but if you give them the specs listed above they can probably crossreference to the right size belt.
