I have the Harrison radiator pressure coolant tank from my 69 Corvette and mounting bracket for sale ($60 shipped domestic USPS). We modified this by cutting the long drop down nipples off the bottom and aluminum welding one at the bottom of each end for a more sleek look.
It has been brushed and painted with clear. It could be polished like chrome, powder coated, or left as is.
It will fit anything you want to squeeze it on. This is what you need IF you don't have a radiator cap on your radiator. Perfect for using in LS1 and LT1 swaps where you use a late model Camaro radiator. Your heater hose line runs through the expansion tank.
It looks like this only the nipples are slightly different.

You can see it on my car by clicking on this link and looking at the passenger inner fender.
