Fan pulley needed

The pulley now in use is 3/8"  groove X 2.37" deep and 7 3/8" OD but the harmonic balancer, alternator and AC compressor pulleys measure 1/2" across the groove. 

I have another pulley that measures 1/2" across the groove X 2.75" deep X 6 1/2" OD.  Due to the depth and OD it interferes with a bracket bolt.

What am I looking for?  Where to look?  Any input or offers considered.  I wouldn't mind a smaller pulley diameter to speed up the fan during the summers here in Texas.  I would consider a pulley with two 1/2" grooves.  Believe the depth needs to stay 2.375".

Thanks

Forgot to mention, I have a fan shroud.  What I need is a pulley with a 1/2" groove.  THX

The ’55 & ’56 harmonic dampers have the ½” wide pulleys.  The belt width went to 3/8” in 1957 and the harmonic damper pulleys were changed accordingly.  Sounds like you just need the earlier damper if you want to stay with the ½” belt.  I don’t believe I’ve a usable damper with a ½” belt pulley but I’ll take a look later today and let you know.

Tom, I have a pulley off a 56 Victoria that measures 1/2" groove,67/8" diameter and 27/16" depth. I am switching to a truck pump so may not need this pulley,should know in a couple days. Let me know if this would work. Mike

Hi, YellowWind.  That pulley sounds like it will work with my 1/2" damper and other 1/2" pulleys.  Let me know when you determine if you will need it or not.  THX  TC

Tom, if you still need the pulley make me an offer and pay the postage and it's yours. Mike

Thanks, Mike.  Traded for one this weekend.
