4 speed mechanism for 69 A body Barracuda with console...
Based on what I've read and assumed, I think @Daves69 linked to the mechanism you need. They are pretty common shifters, as the same unit was used in 1975 and newer applications including A833OD trucks. That version has a grease fitting on the side. Here's a picture of one set up on an overdrive transmission for my 1968 Valiant:
The linkage for third and fourth gears in that photo are different than what one would find on a close-ratio transmission.
This statement is a bit confusing. Do you have the shifter pictured, or do you the similar version with a bayonet mount? I'm not sure what "the pieces to show me to screw it into the three holes" means, but I assume you mean the plate that goes between the shifter mechanism and the transmission. Pictures of what you currently have would greatly help us determine what exactly you need.
