    I recently learned that the difference that starter vendors make between MT and AT is a mistake. The starters (offset) differs for 157T and 164T flywheels. So, you need to order a starter for an automatic in order to get one for a 157T manual flywheel. The information comes from Bob Mannel, so you'll know it's accurate :)

    I have them on my 65 in combination with 80's MkVII/SVO rear discs. I used the Lincoln/Thunderbird/Galaxie calipers, Cobra Automotive brackets, 70 drum spindles and disc hubs and 68 Galaxie rotors (Raybestos 6008)


    I'm still sorting things out, but so far, braking performance isn't spectacular yet. It brakes allright but you have to push hard and there's not much initial bite. However, I recently discovered that the problem is probably in my booster. It's not totally shot, but loses its vacuum initially, which is probably the reason why the brakes feel kind of dead when braking lightly.


    Of course, my problems have not much to do with the front brakes themselves (at least I hope so). At least they look cool and period correct :)

    Sorry for bringing up this old post again, but what is the balance of the replacement dampers? 28 oz, or the Hipo specific 24.5 oz?


    I'm using a replacement on my non-Hipo 289 without the extra counterweight. The whole assembly is balanced, so I'm not really worried about unbalance, but just curious. I do recall that the balancing shop mentioned that they had to make a lot of corrections.

    Although I'm not an expert, I've been around Thunderbirds since I was little (My uncle and cousin have a 64, two 66's and a 69 and all the original brochures we used to look in all the time), and I don't think they offered wire wheel covers on 67 Thunderbirds and not on any earlier years either (although they did offer real wire wheels in 62-64).


    It's probably some other T bird wheel cover (or Galaxie maybe?). All in all, the whole suspension looks much like what the Shelbys came with: they also used stiffers springs, adjustable Gabriel shocks and Thunderbird wheel covers (Kelsey Hayes mag wheels optional).


    A plausible scenario is that Ford just installed the Shelby suspension parts and offered it as an option on Mustangs. The parts were already there and just could be installed without further development. Or maybe Shelbys were fitted with this option as standard equipment? Just a guess of course.


    BTW: maybe you know this already, but the load rate which is often mentioned for leaf springs has nothing to do with the stifness. It is the amount of load that is required to compress the spring a certain amount (usually so that it's flat). That's why a fastback leaf spring typically has a higher load rate than one for a coupe. It is heavier in the back, so the load rate is higher to achieve the same ride height.


    A higher load rate without increasing the stifness can be achieved with a larger arc. That way, it needs to be compressed more inches before it's flat, and since the load/inch is the same, a higher load is required to flatten it.

    All export Mustangs got the Export Brace, hence the name. Some say it was because of the rough roads abroad, others say that it was to avoid body flex when lifting out the cars from the ship with a crane.


    When the Shelby engineers visited the San Jose plant in the fall of 1964 in order to discuss how to organize GT350 production (what they should delete etc), one of them noticed that some cars got stronger braces. Since it looked like a good idea for the GT350, they decided to include them in the package.
