Mirror Mirror on the wall ... Dimension help 70-71

[70cst]

I bought my 70C10 back in 01... in the mean time I have been buying spare parts. Way to many spare parts

My truck is 99% finished and I don’t need 8 sets of mirrors plus a bunch of spare parts that I am starting to go through.

Question: What are the difference between the 70 and 71 below eye line mirror? Thanks

Yes - these mirrors will be going up for sale soon.

68 thru 71 are all same..... 72 has a different (small) upper arm. I believe the lower arms on 72 *may* be shorter also.

in post 1, pic 2: the bottom 2 sets of lower legs are 72 (lower attach points attach above upper trim), the rest of the lower legs shown appear to be pre-72 (lower attach points attach below upper trim).
Mirror heads are identical for all below eyeline mirrors 69-72 (they eventually changed in the square years).
I think the uppermost mirror head in pic #2 is not an original (not the different attach point webbing/stiffeners) - but not certain from the pic.
Note that the mirror head attach point should be centered vertically on the mirror - some aftermarket mirrors are off-center vertically (I'd look closely at 3rd mirror in middle row of 2nd pic in post 1).
Also take close note of the different upper attach leg flanges/angles where they connect to the door - stocker's shows the correct for 72, somewhat flat attach flange .
Most of your pre-72 stuff shows the angled down version (to further identify them as pre-72, in addition to the long lower legs).
I'd look closely at the upper leg of the left 72 mirror in post 1, pic 2 - that upper leg appears to not be original (flat vice round).

Could you please back away and post a picture of that whole truck? The close-up is pretty nice...

Just to add some nitpicking comments...and confusion... to something that probably makes no difference at all.


I also noticed while junk yarding that there are apparently 2 slightly different leg styles and different length brackets from the cab to the legs on the pre-'72 version. What I wondered is if the later style has the slightly sharper bend at the foot of the legs, and the shorter bracket (5-1/4 in. vs 6-7/8 in.) to better accommodate the upper cab molding when ordered present. The attachment points on the doors are identical. I now have those with the slight bend on my truck.

My '69 (Dec. '68 build) also had DG4s with offset mirror heads.

Comparison pics. First 2 are my originals. Third is the one with sharper bend and shorter top arm.
