interesting ,, my 71 has 72 doors from factory
 

has anyone else noticed that the late production blazers in 1971, june build has upgraded to the 1972 door panels and 72 pinch screws at the vents?

Re: interesting ,, my 71 has 72 doors from factory
 

I think they start releasing the new model in august if that’s correct i think that would be too early but I am no expert

Re: interesting ,, my 71 has 72 doors from factory
 

of all my searching i cant find a 71 built any later than june 71. my june build has the original blue door sticker with the vin# and 72 doors.

In those days, sept. was the change over month. I think all of the blazer doors (70,71 and 72) all had a screw under the wing window. Not sure about 69. The earlier ones had a plastic escutcheon with the screw. I think it would be odd for a june 71 blazer to have 72 plastic door panels, but who knows for sure. Alot can happen in over 50years...

Model change for us (Oshawa Assembly Plant) was always in late July right after summer shutdown.

Maybe OP's doors are not original, or GM decided to do a design change part way through model year. We did this quite often.

Would like to see pics of OP's Huey in his signature.

My 70 Jimmy was built in July, it had the screws for the vent windows.

sending pic of my UH-1d



the assembly plant in Stlouis was shorter of production.

Re: interesting ,, my 71 has 72 doors from factory
 

Please post pics of the doors preferably with both the door panels on and off. It's easy to tell if the doors have been modified to accept 1972 door panels.

Re: interesting ,, my 71 has 72 doors from factory
 

Awesome! Thanks for that.

Re: interesting ,, my 71 has 72 doors from factory
 

pics below i seen the date of 6/71 before power washer hit it i will get pics of door panels soon

Re: interesting ,, my 71 has 72 doors from factory
 

this is the correct vin on factory sticker

Re: interesting ,, my 71 has 72 doors from factory
 

Yeah, that looks legit.

Re: interesting ,, my 71 has 72 doors from factory
 

Can you post a photo of the screw just below the vent windows?

Re: interesting ,, my 71 has 72 doors from factory
 

I can't comment specifically on these doors, but in general:

We would pull ahead minor changes in detail components if we thought nobody would notice, or if there was not a decrease in value, if the timing worked out and it was convenient to do so. That would be one more thing to not have to worry about when the bigger model change hit and we could cross it off our list.

Things that were "marketable", like an appearance change (interior or exterior, like a new grille or front end appearance), that we could charge more for, or that were specifically tied to a new model via regulations would break point on the model year.

Re: interesting ,, my 71 has 72 doors from factory
 

Did the doors turn out correct for 71?

Re: interesting ,, my 71 has 72 doors from factory
 

they look to have 72 door guts and panels but are on the original 71 door so either it was dressed up with 72 guts and panels from factory or some one took the time and money to change both door guts and panels to over to 72 style not sure? ??????????

Re: interesting ,, my 71 has 72 doors from factory
 

it is a late june 71 build. the last month of the 71 build for the St Louis plant i belive. so it may have been one of the earliest to receive 72 panels and door guts ?? who knows?

Re: interesting ,, my 71 has 72 doors from factory
 

As I see it, the most likely scenario is. In the past 50+ years someone has changed out hardware to accommodate the 72 door panels which they liked more.

Re: interesting ,, my 71 has 72 doors from factory
 

I converted my 71 GMC K15 suburban to 72 door panels over 25 years ago.
Finding a good set of regulators for the front was fairly easy then, as they are the same as all pickups. Finding rear window regulators for the back windows was another story. After looking for some time, I finally took my original rear regulators drilled out rivets and replaced with longer 72 posts. about 6 months later I stripped a 72 suburban with proper long posts. Those regulators are still on the shelf.
