ALL & Michael,

Here are some shots I took, of a powdercoated Pantera lower pulley, and a
machined anodized pulley for putting a 5.0L motor into an early Mustang.
Has the 4-bolt mounting pattern. (Was looking for a suitable replacement
source for pulleys...)

I somehow missed uploading the overview picture, that shows the mounting
holes, but they appear similar....

      This is probably the most critical picture as it shows the proper
lineup for the inner sheave, however, the AC sheave is closer to the motor
than the one on the original Pantera pulley.  Depending on the brackets,
this may or may not be an issue, I am not sure of how that all fits and
what can be moved if anything.

Overall diameter of new pulley is a hairball larger.  Of more important
note, is that the two sheaves in the stock Pantera pulley are NOT the same
width!!!  My guess is that the wider groove is for the AC belt, and the
smaller for the alternator....

Not sure if this helps at all..... in this case.....
