I don't have it made for the Coupe yet - so it won't be at Spring Thing, and them i'm on vacation for a couple of weeks... and right now I'm on a plane to Detroit (meaning no time to get this done until mid-April. Then, I'll do both version. The version that goes on the end of the hard linkage (i.e. my Wagon), and will get some photos of the throttle cable replacement version (i.e. our '76 spider and '75 coupe). There's a little bit of furtling to do with the throttle cable replacement version to give some slack at the pedal end (it's easy enough, just remove the cable inner, the rubber mount and snip away about 2" of sleeve - then reassemble.

Here's what the cable looks like before any modification. The sprung end mounts either in a fixing that attaches to the intake cam tower (the threaded hole just to the bulkhead side of midway where some throttle linkages affix), or (and this is my preferred approach) a 2-3mm aluminum rod that you drill to mount on the motor side air cleaner covers. A 45 degree twist in the aluminum orientates the spring to the right angle for the balance linkage ball stud. I've worked this out for use with the original weber balance linkage. If you've got something else a bit fruity installed that has the ball stud higher or closer to the motor then I imagine playing about with a squared U shape in the aluminum bar would work the best.

More when I'm back in my garage.

I would also be interested in seeing the finished result. How long is that cable?

Many thanks

Finally found the thread that I'd gibbered about this on. See below pictures from a prototype installation on our wagon (which had a disintegrating throttle cable, NLA, and needed *something* doing to it).

Please forgive the heath-robinson bracket holding the sprung end - I'll fabricate something up to replace that now it's point proven (similarly ignore all the other blemishes with this engine bay - it's a work in progress!). All in all this works really very nicely. The throttles are held nice and firmly close by the spring. The accelerator cable works with standard pressure and opens nice and smoothly. All in all a good upgrade.

Here's what I did:

- take one Fiat Strada throttle cable (still available)
- remove the spring assembly from the threaded stud end
- remove the entire cable core from the green outer (and yellow inner run)
- cut the green outer and yellow inner to the right length and reinsert the cable
- attach the plastic mounting collar to the throttle bracket, reassemble the spring end and attach the bracket to the car
- take the female ball end off of the original linkage (or acquire one if your linkage didn't have one) and thread on to the stock sized stud of the strada cable
- cut the cable to length at the bell crank end, attach a stud end and a new female ball fitting

Next stop for this is the coupe. I think that for the coupe and the spider, the stock end for the strada cable will work as is. The cable is the right length (I hope) and the stock end fits in the top of the pedal.

Hope this is helpful, I'll revert to this thread when I've done the coupe - and Chris and Allen there's a cable in the mail for you right now to add to this exploration.... :)
