Default Re: 64 gmc steering column issues

The LMC is somewhat tricky to read. 1963 is a tricky year.

The cam 34-0770 is for 63 Chevy and 63-66 GMC. The cam 34-0771 is for Chevy 64-66. This represents what I call the "new" style turn signal. The "old" style "cam" was used by Chevy and GMC from 60-62 but 60 is different than 61-62. 34-0050/51

The switch 36-0602 is for Chevy/GMC 60-62 (old style), 36-0603 is for Chevy 63 and GMC 63-66, 36-0604 is for Chevy 64-66

This info by Jolly and TexGMC is correct for switch and cam: "1963-66 GMC used the same as 1963 Chevy trucks."

...and the column horn parts are all the same Chevy/GMC 60-66. Except logo button.
