Delco/NDH bearing S#'s

Going through boxes of stuff after the move, and have several NOS Delco/NDH bearings. I'm guessing they're possibly differential or f/r spindle bearings. I have 1 or 2 each of S5, S6, S7, S8, S9, and S23 bearings in unopened boxes, and a bunch more that I'm unclear about used or unused. Anybody know what part of the suspension/drivetrain they fit?

thanks,
Mike

The S5 crosses to a Timken Set 2
S6 crosses to a Timken Set 6
S7 crosses to a Timken Set 3
S8 crosses to a Timken Set 5
Can't find HDH S9
S23 crosses to a Timken Set 36

Here is an applications list for Timken sets

I always go by the number stamped/etched on the races. If you post them or PM me I can check. NDH( New Departure Hyatt) and Hyatt before that were the OEM for the corvette. Very good bearings, long gone.
