Hey guys after replacing my glass all around on my 70 SS including the regulators it has become evident I have aftermarket handle cranks. It appears the part that goes over my spline on the handles I have is a little short and they do not lock on properly. Any leads a to where to get the proper ones would be appreciated as I want all 4. The one I need is on the right in picture.
eagleguy if you just want the knob to fit and work then there are some inexpensive reproductions offered ($9) that work and look close to the originals but have a slightly different arch than the originals. If you want them to be the same shape as the originals those are now available as well thanks to the Chevelle and GTO guys. They do cost more ($15) and require a little massaging to make the clip to fit right but it's not a big deal. You can see the slight difference in the photos from the Ames Performance Engineering website (pontiac supplier https://secure.amesperf.com/index.html) Even without seeing the bottom of your existing handle I can see the shape (arch) is not the same as an original and knew it is a reproduction part. It might be one of the cheap window cranks from "HELP" section of an auto parts store.
Need the type on the right side as most repos like the one on the left in the photo are shallow, not deep enough.
