67 A/C fan blade/brackets

[Tim Sargent]

Does the 67 427 Air Conditioned car have a seven or five blade fan and if is seven blade is it supposed to have the ends bent over? Also what is the correct part number?
Also the judging manual indicates all A/C compressor brackets are Gloss black in color. My steel compressor brackets are gloss black but the cast iron brackets that bolt to the cylinder block and the exhaust manifold appear to never have been painted is this unusual?
Thanks

The 1967 L-36/L-68 with C-60 used a 5 blade fan of GM #3888366. This is the same fan used for all other 1967-68 Corvettes. The ends were not "bent over". The 3888366 fan was replaced, for SERVICE, about 35 years ago by a 7 blade fan.

I believe that the cast iron compressor brackets used for your application were natural cast iron. I thought that there was only 1 cast iron piece, but there may have been two.

The NCRS judging guide states the cast brackets are painted black. I have found this to be true on one car but have not verified it with other originals.

As I recall, all accessory drive brackets (stamped or cast) were routinely dip-primed black; the small ones were done in bulk in wire mesh baskets, and the larger ones were hung on pins on larger racks. Hollered at the Paint Superintendent more than once for running me out of brackets on my Engine Line
