Hello all,

Just wondering if this bracket had a part number so I can search it. Thanks.

Josep,
It's a C6DE-9B481-A "Bracket, Tube Support". This bracket is not shown on in the 66 Engine Accessories Manual, but is shown in the 67 Engine Accessories Manual. This is probably because the 66 Manual shows the "backfire" style smog equipment and it was added for the later bypass version.  It "may" be held to the engine by one of the coil bracket bolts.

Hi Jim, thanks for the answer. Yes, that's the one.! I'm looking for this bracket (and some others!) to complete a SMOG system for my car, but didn't know the part number to make the search easier. Let's see if I can find it.
Attachment point is the one you said.

Thanks,

Josep

Jim, is there a part number as well for the air pump valve scoop cover..?

Thanks,

Josep,
Yes and no. The MPC says C5ZZ-9B472-A, Silencer, is the one; but it's not like the one in your picture. The MPC shows a more round item about 2 inches long with a "scoop" on the side. It was used on 66 and 67 full size Fords, Fairlanes, Mustangs and Falcons with I-6 and 289 engines with the air gulp system (no 390 applications) which gives you more selection. From what I've seen in junk yards, the silencer is usually not mounted either having fallen off, or eliminated in a rebuild.

thanks Jim, OK on that.

I think the silencer is what appears in that pic. I am looking for the scoop attached to it.
Got that silencer but missing the scoop.

There are a number of different applications and time period affects the type and style of "scoop" used originally. Some applications (V8 included) used not while others used the little round style and others the large triangle style shown in the first picture.

There was also a Technical Service bulletin that showed how the scoop opening was orientated or should be

Will see where that stuff is hiding

Alright Jeff,

The air pump that comes from the V8 system that we have, does come with the round shaped style.
I didn't know there were two styles of covers. We have one, let's see if it's good enough for my car.!

Here are the factory notes showing the different styles of "silencers" and details including a new one added in Feb 1966 production. Hope it helps explain another detail related to the 1966 Thermactor system for the 6 cylinders

Josep, From what I read in Jeff's TSB information, it looks as though your inline 6, since is built AFTER the February date, would originally have had the wedge-shaped silencer , NOT the scoop type, is that the concensus here?

That is what Ford reported in 1966 to their dealers and service shops and what we've found on original cars we have pictures of - unless there is no scoop/silencer (fell or taken off at some point ;)

I'm working hard to find one of those, but not an easy job.!
Got the scoop type already, but looking for the wedge-shaped one.

That 67 setup I sold several months  ago had that wedge shaped one, also the other support you now need. I know one or two of the mounting brackets for the 67 were C7 numbers but a good majority was what would have worked for your later 66, so it seems, so keep that in mind on your hunt, that is to NOT exclude looking at some 67 parts since several are the same.
Also, FWIW, when I did an Assembly Manual Study on those 67 parts to properly understand what all it would fit, it seems that the pulley differs from OTHER potential options on the car and how the setup was shimmed on the mounting brackets (read as move a spacer here or there to move the pump forward or backwards on specific applications e.g. with power steering or without, or with air conditioning or without or any such mix of options)
It was a little confusing but it WAS POSSIBLE to sort out what engineering number an nstaller would use on the pump pulley but you really needed to study the assembly manual's notes. I imagine it isn't much different for the 66 system you are trying to build. I hope you have ordered yourself that Assembly Manual by now. It WILL really help you out A LOT!

That was a shame Richard. But things comes when they have to come, so looks like now in the time for me, with all the consequences. I will continue looking for these parts.
My car hasn't PS nor AC, so should be easier I guess.

Which assembly Manual would you recommend.?
I have the 1966 Shop Manual.
