I am looking to change to aftermarket rear control arms for my '73 Century. I purchased a factory upper and lower arm for 68 to 72 A body's and found the arms in terms of dimensions are 100% identical except for the length of the upper arm. The '73 to 77 A body upper arms are exactly 1" longer. With this in mind, would a adjustable arm have at least 1" or more travel? Who has aftermarket arms in your 68 to 72, what brand do you have, and would you recommend them. There is virtually no choices for arms for us 73-77 guys, but based on my measurements, if there is enough adjustability in the upper arm, there may be many selections that would work for us as well...
I wonder if a g-body (i.e. grand national) setup would work for you. I have the HR Parts-n-stuff arms in my cars, they are fantastic. -Bob Cunningham
I would call HR Parts n stuff, they are very helpful and could tell you whether you can adjust 1". They might also be able to make a special for you (maybe). -Bob Cunningham
