Is it the same trough this series of years?

According to my Chevy interchange manual 68-72 Lemans is the same as 68-72 Chevelle, same years Skylark, Elky, Prix, 70-72 Monte.

The only note: 70-72 could have built-in antenna wire, but the glass would be the same.

Yep. Had a '72 w/s in my '68.
Eventually switched back to the fender antenna- better reception.

Make asure it's a 2 door! I got a great deal on a 4-door lemans windshield at a wrecker, the guy thought it's the same as a el camino or 2-door, turns out it's about a 1/2 in taller and will not fit. I found this out after a removed the cracked w/s in my el co in about 10,000 pieces, so I had to buy a new one the next day, but It was only $110 Jim
