I would pinpoint the leak. Clean front of engine, get it dry and fire it up. If not coming out of the front of the water pump seal, etc. it could be between the front engine cover and the block at the coolant channels (circled in blue in 1st picture below), or the cover and the water pump (circled in green in 2nd picture below). You need to find out where the coolant is seeping from.

1963 RHS A/C kick panel - photos needed

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,

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great!
