For spindles, I started with the 63 Pontiac spindles as advised in the article. ( Tapered bearings and a good Scarebird kit available.) Unfortunately when I set it on the ground, it was too high. This led to a search for dropped spindles. BOP – they don’t exist. | For spindles, I started with the 63 Pontiac spindles as advised in the article.

Chevy drop spindles are readily available, but they come with a problem. Note the side by side comparisons in the picture. The 63 Pontiac spindle has a deep 90* bend at the bottom. That is to clear the wide corners on the lower control arm. The 60’s stock Chevy spindle has a 45* angle there, and won’t work. | Chevy drop spindles are readily available, but they come with a problem. Note the side by side comparisons in the picture.

The third spindle is the 65-70 Chevy drop spindle from CPP (Classic Performance Products). It is their own in house design and is very close to the dimensions/configuration of a Pontiac spindle. I had to trim the ears off the front side of the lower A frame, but that was a minor modification. | The third spindle is the 65-70 Chevy drop spindle from CPP (Classic Performance Products).
