'73 Upper Control Arm

How long, center to center, are the rear upper arms on a '73 Century.

I am looking into getting some adjustable arms and everywhere I look there is a gab from 73 to 77.
The lower arms are the same as 68-72 but how about the uppers ?

 

arms

Rear upper control arms are the same on the "A" body 1973 thru 1977.

 

I know that, my question is, what else will fit since nobody makes arms specific for 73-77

What I got until now.
Upper
A 64-67 = 12.750''
A 68-72 = 10.250''
A 73-77 = ???
G 78-88 = 11.250''

Lower
A 64-77 = 22''
G 78-88 = 19''
