The shock tower delete kits for 1964.5 - 1970 Mustangs are used to close out the stock inner fender panels after removing the original strut towers. They can be bolted or welded in place, are compatible with stock inner fender panels and are designed to mimic original strut towers for a modern appearance. The delete kit provides clearance for Ford Modular engines and most aftermarket suspension systems. Detroit Speed's shock tower delete kits are stamped in the USA from 14 gauge steel.
