Are 67-72 A-Arms All The Same?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Are the A-Arms all the same on 67-72 models? I know that the spindles of course are different on 5 lug and 6 lug trucks, but will the A-Arms off of a drum brake truck work on a disc brake truck??

Also what is the difference between 67-68 Radiator Supports and 69-72 Radiator Supports??

YES they will but you need to use the same year ball joints and a-arm bushings on the disc brake ones that you want to use.
Don't know about the other.

The steering stops on the a-arms are different form drums to disc trucks. if you put a 71-up spindle on your drum brake a-arms, it will cause your turning radius to be longer. I don't think the change is much though. However, I think early classic 67-70 disc spindles are made to counter act this.
