Kris 90 Report post Posted November 5, 2019 I’m drilling my shock towers today for the Shelby/Arning drop. Do I need to weld up the old holes or just leave them? Also, the new holes are pretty close to the end of the support bracket. Will this be an issue? 1 Grabber70Mach reacted to this Quote Share this post Link to post Share on other sites
aslanefe 333 Report post Posted November 5, 2019 You can leave the old holes, or weld them up if you like. Before drilling the full size hole, after drilling a pilot hole, I welded a piece of steel as thick as the support brace to the edge of the brace where the holes are close to. This way the bolts sit on flat surfaces. Quote Share this post Link to post Share on other sites
aslanefe 333 Report post Posted November 5, 2019 By the way, one of the holes on the last car I drilled, the brace was welded a little shifted; so the hole came out the edge of the brace. If you drill a pilot hole first, you can spot this issue before you drill the final size hole. Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted November 6, 2019 Step drills work great for this mod. I glued in some crescent washers to get a flat surface, then used a heavy washer. Most folks just leave the upper holes open. Quote Share this post Link to post Share on other sites
Kris 90 Report post Posted November 6, 2019 Thanks for the info. I got it done today. I’ll probably leave the holes if it won’t cause any issues. Quote Share this post Link to post Share on other sites
