is this good deal on '70 12 bolt?

is there no brake shoe adjustment openings on the '70 camaro 12 bolts? i had one on my 10 bolt but when i went to adjust the brake shoes on the 12 bolt, i don't see an opening.

I'm going to wake this thread up because I'm working on my driveshaft, slip yoke & rear yoke now.

1973Z with original M21 4-speed, 1970 12 bolt rear end w/teeny yoke, and a 48" driveshaft from unknown origin.

I have 2 slip yokes... short and long.
I have 3 pinion yokes. The one that's currently installed (which I'll probably use), a nice 8.5" yoke, and a billet "12 bolt" yoke.

I have the conversion u-joint... that may or may not work.

My current question was if the 48" shaft will work.
This 12 bolt has 4.88 gears. I'm going to live with that for the time being rather than rip it apart and put the 4.10's in it. My yoke doesn't fit on the splined pinion shaft of the new gears.... so... I'm to the point now where I'm going to button it up and see where I'm at.
My initial question was buying the wrong joints, if the shaft is too short.

My available slip yokes are
5.25" & 6.5" long.
I ASSUME the 5.25" yoke will be the one I'm going with?
