I've installed a Speedway bolt-in MII in my '50 3100. I followed the template instructions, measured numerous times before drilling, however, after all bolts were tightened, one side is a 1/4" forward/rearward than the other side. Just wondering if I should just loosen all bolts and see if I can get close to square,(or square), by re-tightening the bolts one at a time if I can get it to move enough. Thoughts and suggestions?
