Little help just got a signaw manual steering gear box with the Pittman arm Like to know what the numbers mean. Came off a 68 chevelle.
Here are the numbers.

5679142
B3348
Pittman arm 5679207A.

Also is there a GM manual steering Pittman arm for the fast ratio box? Or is it the same as number above?
Who sells A rebuild kit with ball bearings ?
By the way this is a 6 turn lock to lock box.

Thanks Dave

I am no expert, but have the same steering box and pitman arm. From what I have read, you have :
5679142---------------------manual steering box cast 310th or 316th day of 1968 ('78,'88?)
unsure about the number 9, mine is number 14
B3348-----------------------machined 334th day of 1968 ('78,'88?) (B-maybe cast second shift)
Pittman arm 5679207A----manual steering pitman arm (B-maybe cast second shift)
unsure about the GMT16, mine is GMT22
Could you possibly put a caliper on the grooved gear and measure the OD? I have a post titled "Pitman Arm Fit" where you can see the pics of my steering box.
Sorry, can't help with your other questions

Tommy will send you photos of my pitman arm how it mounts to shaft. It has never been removed from the shaft. Thanks for the dates on my box.
