Kenneth, See picture below of the mode door spring installed. I do have an extra in good condition for $10 ($7.50 after discount). Email me at jasonedge64@outlook.com

Yes, there is a spring. If you need one I can see if I have one tomorrow.

Do you recall if there is a return spring on the interior side of that mode door? 

I took mine apart and there appeared to be one with one end broken. Just checking my work.

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,

Loud air moving sound within carb with cleaner removed

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