Steering Box

ID tag on the steering box says:

Code		HCC AT
Date		4K08B

According to the documentation found in the internet

Application	Tag Code	Type	Ratio	Turns
65-66 Mustang	HCC AW	Power	16:1	3 3/4
	HCC AX	Manual	16:1	3 3/4
	HCC AT	Manual	19.9:1	4 5/8

And the interpretation of the date code is:

1st digit		Year	4	1964
2nd digit		Month	K	October
3rd and 4th		Date	08	8th
5th		Shift	B	B	(the second work shift of the day)

Based on the dates, this might be the original "slow-ratio" box installed by the factory.
The basic reconditioning took place with the steering box. Cleaning, painting and greasing, that is.

Good instructions how to lubricate the box can be found on Stangers' site. In brief it goes like this. 

1) Turn wheels all the way to one end 2) Remove fill plug and the farthest screw 3) Press grease in until it squirts out of the screw hole 4) Turn wheels to the other end and repeat the steps.
