The question I already asked was isn't the JB7 the most powerful vacuum booster? And are the pages you printed showing the "DA" is a JB7
Yes, and yes.

240S = single
240T = "tandem" = dual
So you have a "double" already.

Absolutely.

The booster label is "DA"

There is this from earlier
Vacuum-boosted:
JB5 = Power Brakes, Disc/Drum, 6,400 lb
JB6 = Power Brakes, Disc/Drum, 7,200 lb
JB7 = Power Brakes, Disc/Drum, 8,400 lb

The page posted by Keith lists under the JB7 column the booster as
18024268/DA
Is that the sticker on it?
Yes

Because aaaaaaaaaaaaaaaallllllllllllllll those other components listed on that chart make up the brake system; not just the booster.
