spindle bearing sizes?

[suspect]

are the inner/outer spindle bearings different sizes for light duty and heavy duty?

i ordered bearings from summit.com for a 72 c10 2wd. i got them today and they are to small for my spindles and rotors. i double checked the part numbers with summit and it shows them to be for light duty brakes. i looked at a few other brands they have and their are some for heavy duty brakes.

i have cpp 12" diam. x 1 1/4" thick rotors, mcgaughy's 2 1/2" drop spindles, and wilwood d52's.

thanks.

One of the two bearings is different.
I can't remember if it's the inner or outer bearing.

both bearings are smaller than what i need. i'm just going to return them and go to a local bearing supplier that my work uses. that was my original intention, but it's a little to easy to just order off the internet when your already sitting in front of the computer.

thanks guys.
