You can help header clearence by using a 1967 Camaro idler arm, its around 1/4" to 3/8" longer & will push the center link forward. Use the long pitman arm on the drivers side. Rick's Camaros has the idler, or check Rare Parts.

Thanks David. I spent a lot of time on your site and other forums studying the different lengths of pitman/idler arms prior to ordering up the Moogs. I ended up with the longest of both that I think I could get without going to the Rare Parts brand. I just couldn't see the cost difference being worth the small length difference. I went with the 6582 pitman and 6099 idler. I had no luck locating the 6093 idler.

I hope to get time to mock up something to check tru turn clearance after the holiday. If it were just a hair off the I might would try the longer idler arm. I'm thinking it won't be close though. I like what you guys did in this area on the OLC. Since it doesnt bolt onto the OE drag link that saves 1/2".
