ash tray to drink holder conversion

[zacut]

Has anyone tried the ash tray to drink holder conversion from Classic Parts or Brothers? I am interested in this and looking for advice or instructions. Neither site has much information, but Brothers does say some modification required, no other information. Just wondering what is involved and how well it works.

Question 2 - I know the later trucks have bearings on the ash tray slides, but do the 67s? I think mine looks slightly different than the standard bearing slide pictures.

Anybody with the conversion in a 67?

Thanks
