    Does anyone have a clear photo of the left hand side of the carb installed with the throttle linkage fitted and the correct return spring and bracket?

    I've searched for many days on the internet and not found a clear picture.

    I have the correct spring and bracket, but it's not clear how they fit.

    Car is a '67 GT350 #2751

    Many thanks for your help

    This ought to be clear enough. Look at the lower half, for the "4 barrel carb" note. Ignore the year, it's the same.

    That would be the correct illustration under 4 barrel that was kindly posted. The bracket that bolts to the carb nut is different but Jim Cowles of Shelby Parts and Restoration sells a nice repro . The best of luck. Bob

    Yes, there are a number of different versions out there. Even if yours is not "correct", the basic configuration is the same, so you should be able to install it.

    Hmm... something not right here.

    I tried to assemble the bracket and spring as shown in the diagrams but it's not right. When positioned as the diagram, the bracket sits on the cast web that is strengthening the carb base fixing 'foot'. (Sorry I can't upload pictures - done it before, but the website won't let me do it now...).

    The bracket is a simple right-angled strip about an inch and a quarter long with a fixing hole at one end, and with about a three quarter inch up-turn with a smaller hole in it to attach the spring. The up-turned end is slightly radiused.

    There is an anti-rotation tag on the right-hand side of the bracket, but this points upwards and doesn't locate into any part of the carb base.

    There are no numbers or markings on the bracket.

    Looking closely at the bracket, it appears to have been bent and/or straightened at some time in it's life, so maybe it was a different shape originally. On page 28 of Tom Corcoran's book "Shelby Mustang" there is a photo of a '65 GT350R showing the bracket, but this has the tag on the left of the bracket, and pointing downwards - pointless (?) but different to mine.

    Surely someone must have a photo of a '67 GT350 with the correct installation?

    I'll keep trying to load the photos of mine, but in the meantime, thanks for any assistance you can offer.

    Something IS not right here- Your bracket has been "hosed". The diagram is correct, someone has bent the spring tab on your bracket the wrong way, then installed it upside down. I could stop by a local Mustang restoration shop today and take any number of photos, but I have worked on such cars for years, and the 67 Shelby spring bracket is installed exactly as the diagram shows, so if you are not willing to look at the diagram, and take my word for it, I have to wonder if you will accept any photo I provide.

    This is a 289HP, but the spring, bracket, and rod were also used exactly as shown on the GT350:

    No no - please don't mis-understand me! :eek: The error is not with your advice or the diagram! I am quite happy to accept that you are correct.

    The thing that is wrong is my bracket. It's either the wrong one, or it's been modified, and a picture of the correct bracket and/or an installation picture would clear this up immediately. The photo you have posted is a big help. I now suspect that the bracket has been modified as you suggest and 'reversed' for some reason.

    The closest I can find is in the NPD catalog page 123 pt#9741-2A or -2B, but both of these look like they have two folds in them, and the notch is on the left, not the right like mine.

    As I'm in England, I can't run down to the nearest Restoration Shop and look at the parts they have there, so this forum is one of my few resources - please be patient with me...:eek:

    Ah, England. Spent 4 days there once. No connecting flight at Heathrow, they wanted me to take a "standby". Then I started to wonder why I was trying so hard to leave, I didn't have to be back 'till the end of the week. London-Brighton-Portsmouth-Herndon etc., you can fit in a lot when you keep moving.

    Anyway, the easiest is to re-bend your bracket to match the diagram.

    As for it sitting slightly skewed on the carb base, I seriously doubt that bothered Shelby. If you've ever looked at the rear panel where they cut it for taillights, you know what I mean.

    I gave these guys, replacing a 69 taillight panel, a hard time, because it was cut WAY too straight:

    Yes, you're right. Looking at the bracket again I can see where the old folds used to be. I'll re-bend it.

    You're also right about the tail panel - cut my hand on mine once!

    Next time you're stuck at Heathrow for four days, let me know and I'll take you out in #2751 - I live about 1 hour from Heathrow!

    Many thanks for your help.
