I did order 32 of them and the reply was that they were a discontinued item and to look elsewhere

I received 16 of these today... looks like the real deal. Placed the order Thanksgiving weekend sometime. When did you place yours?

The dimensions on these: 3946246 rectangular mounts: http://www.gmpartsdirect.com/results...number=3946246

are:

3" long
2.1" wide
3/4" thick

What I currently have on my 65 Burb are 3" long x 1 3/4" wide. Steel spacers are 1 3/4" as well.

I thought these 3946246 were what I needed . . . I believe I can use them, looks like there's room in there between the channel.

Anybody got the dimensions for these from Classic Industries? Wondering if they are 1 3/4" wide vs 2":

From previous: "This is what I discovered: 1964-6 body mounts are p/n 3794779, w/dimentions of 1.76" w; 3.00" l; 0.92" thick, needing 8 (up & lwr same). The 67-8 p/n is 3909351 up & lwr, 69-72 uses 3909351 as the lwr, but p/n 3946246 is the upr. No dimentions are given for these cushions, and it seems that the frame changed in '69."

Not clear what the GM P/N is for those cushions sold by Classic Industries...

here is what I orginally posted
the following is what Lewis Matkin sent to me. the pictures are mine and
I will have some more later for you as I have to check something out

Ron, this is Lewis. Please forgive me for not getting back sooner, but I
have been busy in my work for the church I serve. I checked both my
65-66 parts manual and my 67-72 parts manual. This is what I discovered:
1964-6 body mounts are p/n 3794779, w/dimentions of 1.76" w; 3.00" l;
0.92" thick, needing 8 (up & lwr same). The 67-8 p/n is 3909351 up &
lwr, 69-72 uses 3909351 as the lwr, but p/n 3946246 is the upr. No
dimentions are given for these cushions, and it seems that the frame
changed in '69. Qty's in 67-8 are 16, with 69-72 requiring 10 of each.
If you have dimentional axcess to the later cushions, these 64-66
dimentions should help you. Like you, I suspect that the 67-8 cushions
will work, but there is no superseded p/n's between the body styles. I
can tell you that years ago I bought cab mounts for my 65 and the p/n's
had superseded to the mounts for the 67-72 cabs. I hope that this info
is of some assistance in answerring this question.

the dimensions sound right. the .92" high includes the raised section
around the bolt hole.
The measurement excl the raised section is between about .73-.74" high
hope that helps
ron
if you have trouble reading this or understanding it ask
that raised section adds about .200 " to the height

no one ever reads the whole thing do they

Talked to Classic Industries, their PN # G2423: http://www.classicindustries.com/truck/parts/g2423.html
measures 3" x 2.1" so it looks like they are the same as GM p/n 3946246: http://www.gmpartsdirect.com/results...number=3946246

I'm wondering if mine are the original mounts, measuring 1 3/4"
