Wheel bearings

[timkins]

I have a 32 Ford sedan with a Mustang II front suspension on it and a couple of years ago I installed the "Big Brake Kit" on it.  It came with everything to install, 10" rotors and bearings and the rest of the installation. I put the papers away and now I cannot find them for specifications for the bearings and grease seal. The rotor which I THINK is off of a Grenada but I am not sure of that has the markings of BPC 5645501C3P stamped on it. The outer bearing  has LM 12745  DL on it with no markings on the inner bearing. The seal is marked 6815. What I am trying to do is compile a list of what the actual vehicle make, model and year is so I can go to a parts store and purchase them if I need to. Any help would be appreciated. Thanks

I dunno if this will help but I have on my actual Must II front end (stock spindles) with actual Granada rotors : Outer bearing  Timkin LM12749
                                                     Inner bearing       "    L 68149
I don't know what seal....

My Mustang II spindles are stock also. The outer bearing may be the same as the last number on mine is a little bit obliterated. There was no number on the inner so I will try the one you sent. I think the seal will be a little easier to obtain as there is a number on it. Thanks for the help. Tim

i posted these a while back...  they will probably help..




the seal you have is a direct part number.. in most brands.. there are dozens of applications for it...




Timken/Wheel Seal - Front
Part Number: 6815

i keep forgetting if you are running a stock MII front rotor or something else..

it will take a little while but i will cross the granada rotor and the mii rotor and see what i come up with for bearing sizes..

Thanks Wayne, I am printing the table you posted as I write this. I did upgrade the size of the rotors to 10" as the originals were only 9" I believe. They are on stock Mustang II spindles also. Thanks for your help.

hmm..... how about measuring your spindle diameter where the inner and outer bearings ride...

i don't know if you can make heads or tails from these numbers.. they make sense to me...   i left out the metric measurements to avoid confusion..
