1968 firebird steering column creaking/squeaking when turned slow, fixeable???

[68firebird]

my steering column creaks like a ******* when turning slowly, it sounds like its down in the column rather that up to near the steering wheel. is there a rebuild kit available, or is it just a matter of taking the column apart and cleaning and lubing it all back up? I pulled the wheel off and sprayed some lithium grease on the shaft that I could get to. thanks.
