If the clearance hole is 1/4" or more, we usually either throw the rack away, or weld in replacement rails that are properly and accurately drilled. The bad screws and horrible tolerances simply can't be lived with when the gear weighs 80+ lbs and is on ball bearing sliding rails just so you can pull it out and clean the heads of a tape deck. Those days are about over since hard drives have replaced tape cartridges for the most part today, but that is what I had to deal with on a daily basis 20 years back up the log. The predrilled rails, 4 to the rack are expensive enough that after the first one I welded up, the rest were recycled and new ones bought, it was quicker and about a wash for cost.
