Depending on how dirty and neglected the old system is, you'd probably need 4-6 quarts to flush, fill, and bleed. Over buy and then return what you don't need.
How many quarts do you need for a flush? 77 corvette
When I flush the system for track days 78 corvette with a wilwood calipers usually 1.5 quarts is a complete system flush. Flush until color changes.
Now to reduce fluid required, flush the longest lines first to shortest line.

So that is a 48 oz. thanks cagotzmann. What type of bleeder do you have?
yes ~ 50 OZ for us in canada I purchase 3 bottles which are sized @ ~ 500ml 1.5 liters for US standards ~ 1.6 qts
here is the beeder setup I use. Apply ~ 20psi at the MC to bleed the system. Also I attach a 6ft plastic tube to the bleeder and bleed ~ enough fluid to travel 3-4 passes of fluid down the 6ft length of tubing before filling the MC Again.
add a bubble in the line until it travels the length of the tube 3-4 times.
No, the fronts and rears are on separate reservoirs and lines (circuits).
You'll just need to bleed the one caliper line you opened to atmosphere. Unless... fluid leaks out of the reservoir compartment completely. Then you'll be bleeding both on that circuit.
Hi fake, I did mine on our '68 last spring. I started with a completely new system - mc, calipers, hoses, lines, etc. I had 3 quarts on hand - bled them 2X and used about 1 3/4 quarts - but I also was pretty nuts about removing all the bubbles. I'd have 3 on hand so you don't run out. You probably already know this, but most people don't keep any opened bottles of brake fluid because, once open, the theory is that it will absorb water. Not sure if it's true or not, but I follow that just in case. Best, Paul
