That is only for the C7AA bracket. I know JD knows this but for others ,small letters/numbers =TRW ,large letters/numbers =Ford Thompson. I want to read more about the different alignment Scode67FB says that a C8 marked bracket has compared to the C7 bracket.

(Bob has forgotten more than I'll ever know on these cars!)

Also, for those wanting to match bracket, as Bob has pointed out, to the pump...
Ford Thompson = the Teal-ish metallic blue power steering pumps and
TRW = the Black power steering pumps.

The tag on the back of the pump in the middle line has either a "F" for the Ford Thompson or (IIRC) a "W" for the Black TRW pumps.

Wow, thanks for the pictures
My bracket does not have a casting 'hump'.
The lettering is quite small and has the following

Top Line:    very small and faint  '67'
Bottom Line:   DD 53001-1

Thanks
Randy

Randy, looking at your photos it appears that you (maybe) missing a stamped sheet metal part that goes on the back of the pump and is captured on the stud and sandwiches between the back of the bracket and the correct spacer, see attached image and then look at the left and center images in the second photo of reply #11 on the first page of this thread, also in reply #15 (this page) it is shown captured by the large nut center on the back.

Yes, I have that piece thanks to Bob G.
Just haven't put it on yet.  Even the thickness of that bracket won't take up for the 1/4" spacer.

And so for clarification would 1967 Shelby #23 have used the power steering mounting bracket with the large C7 letters or small?

And here are the numbers on my 2 pulleys.

It could have ether. A large percentage of early cars had the small letter bracket and TRW pumps.

Finally found the C7 numbers on my P/S Pump Bracket.  They were hidden by the black bracket.   Has the C7 in small numbers.  So I guess it is the correct one.
Back to being stumped.

His post mentions nothing about the aluminum bracket. He states he has a "C7" crank pulley. He may, though, in fact have the "C7" bracket if the PS pulley is too far back. The "C8" bracket would put the PS pump pulley farther forward. A pic of his pulley alignment would help.

You're right. I misread that sentence.

The 60-68 MPC makes no note of a difference between 67 and 68 aluminum p/s pump brackets. But we all know how accurate that can be. I have three 67 versions (small and large script) of the C7AA-A version. I parted out a few 68s but i have nothing with a 68 part number.

I'd be interested in a dimension on the long bolt portion of a 68 aluminum version.

[I have measured the large and small letter versions and I find no length difference at the long bolt area of the bracket.]

I'll try to get the "C8" bracket out tomorrow and post pics of it for comparison. It's actually off a 68 429 engine, but it looks identical to the "C7" bracket (except for the additional depth). The same PS pump will mount to it, and it almost looks like it could be used and line up correctly without the spacer. I don't know if it was used on anything other than the 429. I don't this bracket is the issue the OP is having If it were, the PS pulley would be sticking out too far.
One thing, though from his pics, shouldn't he have a two-groove water pump pulley and have the PS belt go over the water pump to the crank? I've never seen a setup that only ran between the PS pump and the crank.
. For his application of 67 GT350 the single sheave pulley is correct.
