The factory coolant over flow won’t work for my setup with my charge pipes. I want to get one that will fit by the passenger side head light but i’m having difficult finding one. Does anyone have any advice?

 

I plan on using this kit in my 70 Convertible Cutlass. Not sure if it will work for your application. It does appear to be smaller and about ten times cheaper then the 68-72 one. https://www.ebay.com/itm/29641241557...Bk9SR8qD96CMZA

 

I bought a similar one at AutoZone.
