Hello everyone, other then the doors and rear view mirror, are there any differences in the '71 and '72 CST Blazers? Thanks.

The one thing that comes to mind are the turn signals/side markers. 1971 Blazers have the full side marker, the 1972 have the split side markers.

Door design and Door panels.

I think the outer grill shell has a black stripe on the 71 and the 72 doesn't. Maybe it's the other way around - I'l have to look at mine later.

72 Blazers have frame horns that go all the way to the rear bumper. 71 Blazers have rear bumpers supported by brackets that bolt to the shorter rear frame section.

The 2 styles of marker lights are related to trim level so CST would get the split style in both 71 and 72. Correct?

Also transmission shift modulator TSM relay is on passenger side of firewall in 72 and engine side in 71.
