This is the fourth installment of our Restoration Mistakes series, dealing with common mistakes made when building or restoring a classic Mustang and how to avoid them. As we said at the beginning of this series, “We’ve been horsing around with classic Mustangs for more than four decades and have come to the following conclusion: we’ve never stopped learning from our mistakes nor have we stopped making them. When you’re restoring a classic Mustang or building a hot restomod it is important to see the pitfalls before you find them, not after stumbling and falling into them. Silly stupid mistakes we make time and time again. Whatever your reason for screwing up, we’re here to remind you we have been there ourselves and know how not to make the same mistakes again.” Our fourth tech tip deals with:

Premature Door Panel Installation

This one has bitten us in the posterior a number of times. Never install door panels and quarter trim panels until all the window and door adjustments are complete. Few things are more frustrating than having to remove door and quarter trim panels because windows are not in proper adjustment. Give doors and windows shakedown time before installing door and quarter trim panels. Run windows up and down repeatedly. Drive your Mustang and take it down a few bumpy roads to allow the windows and regulators to settle in. Then, check window adjustment one last time before installing panels. No matter how perfect you think you have door and window adjustment, a hard shakedown will prove out your adjustments because classic Mustangs are not zero-fit build cars like the new ones. Classic Mustang fit is sloppy and tolerances are loose. Give it a good shakedown before buttoning up.

Mind rolling that window up?
