You need a dual disc master. Like from a dual disc corvette.

It say disc/disc ?

It does!
But I see it fits chevelles, Camaros and firebirds that didn’t have rear discs.
That suggests it’s your typical universal fit part.
The old if it bolts on it’ll work scenario.

Says for disc brake conversions, no 4 wheel disc brakes on 70 trucks so at this point isn't it all universal

Using universal parts inevitably leads to having universal problems.
Time will tell.
Best of luck.
