This what we mean by loose glass in the doors of a '69 Mustang. The best way to solve the problem is to do exactly what Ford did for 1970: replace the glue-in glass with '70-type bolt-in glass. We had to improvise along the way, but once we had all the parts, the conversion on both doors took about a day.

We try to cover a wide spectrum of the vintage and late-model Mustang hobby in our how-to articles. In this case, we have a special treat for those of you who own a classic '69 Mustang.

The '69s (and a few early '70 cars) are the only years of Mustang that Ford glued the door glass into the mounting plates attached to the window regulator. While the '69 Mustang is unique in many appealing ways (for one thing, it's the only vintage Mustang with four headlights), it's also unique in this not-so-great way. Our experience with a '69 SportsRoof was irritating. We tried gluing in the glass, only to have it come out again after a few months. Furthermore, having the glass flopping around in both doors quickly became annoying.

The problem was solved by the folks at Muscle City Glass with reproduction door glass for '70 Mustangs. However, the glass is only part of the picture. You also need '70 plates to attach the glass and regulators together, which we procured from Mustangs Etc.

Finally, we called on Scott Drake Mustang Parts for a set of '70 window regulators. Although they look nearly identical to the '69 versions, there is a slight difference between the two; but you may be able to make the '69s work.

There are many other details you need to know to complete this swap, and we've done much of the R&D work for you. The accompanying photos and captions explain the particulars.

What Glass For What Body Style?
There are two shapes of door glass for '69-'70 Mustangs, as there are with the '65-'68 cars. Coupes and convertibles share the same shape, while fastbacks have a unique shape. Muscle City Glass carries both.
