Hi,

I have Ford Service Part brackets and they are black.

looks like they were dipped as there is a paint run

on the backside.

Can anyone tell me the part numbers for the fan shroud fasteners where they attach to the radiator brackets? I'm trying to order appropriate screws/washers/clips where the shroud meets the clips and can't seem to find part numbers in either the Olson or MPC books.

Finish on the fan shroud brackets: it looks like they may have had a black anodizing or were they dipped gloss black?

Finish on the radiator petcock: were they painted with the radiator or natural?

There's not too much good news here on the shroud bracket hardware. What I've found on my 'K' car was this: the 5/16-18 nut clip that was originally installed on the radiator was put on the shroud bracket and the original 5/16-18 screw came thru the radiator support to hold the radiator to the bracket. There was a second 1/4 nut clip on the opposite end of the bracket for shroud retention with a 1/4 screw. Notice the apparent lack of specifics. Time has replaced a lot of parts. Ford assembly documentation is missing for 'K' cars so the best info is for the air conditioning setup which is also lacking. Only one of the hardware items is available from AMK Products, the 1/4 nut clip.

Here are the various Ford hardware part numbers, descriptions and use:

- 378180-S2 5/16-18x3/4 hex screw, washer head, serrated, lead point, radiator support, radiator to bracket

- 380020-S2 5/16-18 nut clip, .96L, .67W, attached to bracket

- 39881-S8 1/4-20x1/2 hex screw, washer head, thread forming, from shroud to bracket

- 375803-S2 1/4-20 nut clip, 1.08L, .56W, attached to bracket

What I've found for the shroud to the bracket was:

- 31497-S8 14-14x1/2 hex sheet metal screw, washer head

- The nut clip was the 'U' type and I don't have a part number.

Anybody else got some input?

I suspect the fasteners are not original.

MCA Rules:

Fan Shroud: Required on all HiPo and A/C. Rubber pad stapled to battery tray side of shroud. Flat tip shroud attaching screws.

My hardware references are:

- 1966 Ford Products Engine Equipment Assembly Manual, AM0156 Pg 126 for shroud to bracket installation.

- 1965 Mustang Body Assembly Manual, AM0006 Pg 11 for standard radiator installation.

- AMK Products Guide to Ford Fasteners, Pgs 41, 75, 149, 202 and 212.

- AMK Products also lists a Radiator Fan Shroud kit, p/n F-399 consisting of 8 pieces for 1965 and a different kit for 1966, p/n F-401 also consisting of 8 pieces. I believe the items supplied are the 4 screws and nut clips that attach the shroud to the brackets. The description for the 65 hardware is 'AB' which is the sheet metal type. The description for the 66 hardware is 'T1' which may be the blunt tip 1/4-20x1/2hex screw. This implies a different type of hardware for 65 and 66 which may not be consistant with MCA rules, but MCA has been known to be wrong before.

- There is a third kit, p/n F-396 consisting of 8 pieces used for both 1965 and 66, for attaching all radiators to the radiator support.

Having done business with AMK, they have been more accurate with the hardware they have supplied than other sources. There are a few discrepancies in the items supplied however - they use the service parts instead of the original. Keep in mind that AMK supplies hardware and kits to most Mustang parts suppliers.

.............. The picture of the original 66 above are on a car that Ron Bramlett has owned for many years and he is the second owner.

Unfortunately the engine compartment was redone on that car. Wish Ron had not chosen to do that
