I am going to convert to the tall spindle set up and build new A-arms for my chevelle. To make life a bit easier I was wondering if anyone has the dimensions of the stock a-arms, the mounting locations of the a-arms etc. Thanks for any info

Checkout this (http://landry-family.com/arms.html) page. Chad built his own tubular A-arms. Also, he has a drawing that he worked from to build his arms at the bottom of the page.

Hope this helps.

consider these adjustable uppers. http://members.aol.com/smartasreality/page12.html
