Can anyone id this rotor ?

[UK 58 apache]

Hi,
I've got a 58 stepside, but the frontend has been changed , I've been told possibly to a c10, no idea of what year.
This is the rotor but I can't order replacement parts until I find out what it's off?
It's a 5x5 pcd with 1/2" studs if it helps.

If anyone can give me an idea , would be much appreciated .

Many thanks


I'm hoping my photos come out, new to posting photos,

Might post a pic of the suspension. Kinda hard to guess at a rotor, as they can be machined for different specs/cars. Given it is a 5x5 c10 would be a possibility.

Edit...a quick google of the "5516 rotor" turned up a C10 rotor. You can see the 5516 cast into the rotor lip.

Someone else might be able to get this one quickly but I can't confirm the application based on what I see in the picture. The rotor you're asking about, 73-87 trucks, does have the same bolt pattern and stud count. The minimum thickness published in my listing is 30.99 mm and it looks like the stamped number in your rotor is 30.8 or 30.6? It also looks like your rotor has a Ford dust cap but there are no Ford rotors with 5X5 pattern that come anywhere near the thickness on your rotor.

I'd suggest providing more information. Lay the rotor on a flat surface, wheel studs up,and measure the distance to the outer edge (the "top" by where the bearing goes). Measure the outside diameter as accurately as possible. Get the numbers off inner/outer wheel bearings and get the wheel seal number as well, if possible. With those numbers I am fairly certain I could find the application.

Edit: Yep... the Duralast rotor page linked above shows the same minimum machine as what's on the rotor. It's thinner than OE spec which probably isn't good. What's even more scary is that you can find those rotors on ali-baba.com for $5 - $10 each.

Many thanks for your replys, I've taken some more photos, after uploading them I remembered your side of the pond is inch feet not metric. Very sorry.

The bearing numbers are as follows,
48548
48510

12649
12610
Thanks again guys,

That's another thing, I can get the bearings ok over here, but the inner seal in the photo I can't find anyone that stocks them in the UK.
You can see it would be so much easier to order parts if I could id a year and model from the brakes / axle.

Def looks like C10 and wheel bearings # are for a C10.

We can handle metric dimensions over here. Just yesterday I told one of the kids in the shop I was a millimeter away from sending him home for the day.

Seriously, many of the brake dimensions are now published with both dimensions. Rotors are made in China and sold worldwide so it's just easier to list the metric numbers.

I agree that a 1975 C10 is a good application to use to buy replacement rotors and related parts. GM used the same parts on over 600 make/model combinations according to my parts list. You can use Amazon.com or this Ebay page to compile a list of alternate vehicles in case your parts supplier doesn't list the truck.

I have shipped parts to and received parts from England in the past. If you're having trouble obtaining what you need don't hesitate to ask.

that is a 63-87 C10 CPP modular drop spindle in your picture where you can see it says "PP". You will need to call CPP for bearing and brake parts interchange to be sure.

the front crossmember also looks to be a 63-66.

Thanks for all your help and information guys, very much appreciated.

I'm not sure you have Amazon over there but one can get a National 8871 seal through them http://i173.photobucket.com/albums/w...p/DSCF3051.jpg

Specs on that seal are
National - Wheel Seal
Line: NAT | Part # 8871

3 year limited warranty
UPC: 724956190492
Oil Seal
Front Inner
Housing Bore (In): 2.562 Inch
Housing Bore (mm): 65.07mm
Outside Diameter (In): 2.566 Inch
Outside Diameter (mm): 65.18mm
Width (In): 0.220 Inch
Width (mm): 5.59mm
You might find one with the right measurements but no lip on it that would work.
