A suspension and disc brake upgrade on a 1937-'57 Buick, Olds, or Pontiac (BOP) is complicated by many variables and side issues. In addition, there is little information on the topic, and few aftermarket parts are available. | A suspension and disc brake upgrade on a 1937-'57 Buick, Olds, or Pontiac (BOP) is complicated by many variables and side issues.

Also, we do not have a '58 Olds available to check/measure the lower control arms. What we DO know is '57 is king pin, and '59 is all-new. So '58 is it. We used the '58 Pontiac upper control arms simply because we got the whole front end. Several uppers will work, as it looks like '58 to '60 BOPs all had the same basic dimensions on their upper control arms. In fact, the '58 Buick uppers we used on one conversion had some built-in twist that allowed us to add more anti-dive than we could get with the Pontiac uppers. | Also, we do not have a '58 Olds available to check/measure the lower control arms.

As you can see in the photos, the '58 control arms are more substantial than the '41. However, all the dimensions are the same. | As you can see in the photos, the '58 control arms are more substantial than the '41. However, all the dimensions are the same. | ||
