Left driver side is the same from 1961 to 1964 (all body styles) + 1965 (75 Series)
Right passenger side is different between 1963 and 1964.

The RH 1963 is a one year only manifold, while the RH 1964 manifold was also used on the 1965 75 series.

You can see the distinct differences between the RH 63 manifold (top picture) and RH 64 manifold (bottom picture) below:

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,

-Samu

Loud air moving sound within carb with cleaner removed

Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
