I have looked at every 66 engine picture on the ultimate GTO picture site and I still don't know what dipstick. I have a 66 389 w/ tripower and a/c. The NON a/c car appear to have the dipstick that has a very short upper tube. Looks like it comes out of the block below the plugs. I can't see where the dipstick comes out on an a/c car nor can't figure where it attaches.
I also don't see where anyone sells a repop for this application! Can anyone help? a picture would be great.
I am using a 65 upper tube now but it has no where to attach it to the block or the compressor.
