'71 G10 front rotors on '73-'87 drop spindles

[olsofti]

I want to use wheels with 5x4 3/4 bolt pattern that I all ready have,on my '64 C-10 with '73-'87 drop spindles.
Does anyone know if the '71-'74 G-10 rotors and calipers will work with these spindles?
Thanks in advance.

Don't believe so...but you can check out AZ, Advance or O'Reilly's websites and look up both applications and see if they are the same part number. If memory serves me correctly I believe the newer spindles had a larger inner wheel bearing if it was the JB5 brake system.

Thanks Rust. I looked up the bearings and they do have different part #'s. I guess I'll get the truck rotors and drill them to the 4 3/4 bolt pattern.
