1976 was the last year that Corvettes were available with non power assisted disc/disc brakes. The mc from that year and some years before it is a great upgrade to the M715. Both lines have the same piston diameter so equal pressure is sent out. You need to make a new line that goes near the block the brake light sender is currently mounted. Disconnect the rear brake line from that block. Plug the hole and connect your new line from the mc to the rear line. Bleed the brakes and drive.

Unless you lengthen the brake push rod about 3/4", you will have a low pedal before you even start to apply pressure to the brakes. Many have cut the stock rod, added metal and rewelded. I have done this swap and didn't lengthen my push rod because I plan to add Hydroboost in the future and don't want to figure it out twice.
