Ol' Roy had this reservoir on it when it came to me. I decided to leave it in place even though i prefer a slightly different design.
It's in the same location as John's and work's perfectly.
I've installed coolant reservoir recovery tanks on several antique vehicles and always use this particular one.
Dorman #603-001
I like it better than the one that's on the truck because it has two mounting ears instead of just one. It also has the tube in the bottom instead of a tube attached to the cap making it easier to fill.
They're available anywhere but Rock Auto has the best price last time I checked ($8 instead of $23). That's it in the last photo on my '66 Toronado.
