1965-1970 Classic Mustang Strut Tower Brace Install

Last Updated December 4, 2023 | Bill Tumas

Adding a strut tower brace should be at the top of the mod list for your Classic Mustang. They're essential because they stiffen up the front end of your chassis and reduce chassis flex. Also known as a Mustang Monte Carlo bar, a strut tower brace helps improve handling. Strut tower braces can be considered cosmetic mods too, as they improve the look of your engine bay. If you're looking to add one to another Mustang, we have strut tower brace installation guides for S197 and Fox Body as well.

Tip: If your apron is damaged, warped, or otherwise not flat where you're going to be installing the strut tower brace, hammer it flat so the brackets included in the strut tower brace kit are relatively flat. You can have a bit of play, but too much is not good. Also, be sure to use something to protect your paint when hammering.

Step 1: Measure to Ensure Clearance

Before drilling any holes, use the tape measure to ensure that both brackets and strut tower bar properly clear anything in the way such as a distributor. Then, mark where you're going to drill the holes with a marker. Repeat this step on the other side.

Step 2: Drill Holes

Using the 1/8" pilot bit, drill two holes for the bracket on the inside of the engine bay. Then, take the additional support bracket and ensure it lines up with the pilot holes inside the fender. Then, widen the holes to fit the hardware that comes with the kit. Repeat this step on the other side.
