+1 that it will only release a fraction of an inch. If it doesn't pop when the screws are pulled, a few careful glancing blows with a soft-face mallet or dead-blow will worry it apart. Or, you can put the screws back in about 2-turns out and pop them with a brass drift to separate it. I would note the parts positions (especially clutch stack and shim locations) during tear-down to verify it's together correctly in-case it's been apart before. I grabbed one at a swap meet once that someone had apart and just stacked all the clutches and steels randomly, which of-course would have been a disaster if used as-is.
I see that one was made at the Michigan Casting Center so it should be a later Traction-Loc. 28 or 31-spline? Most likely 31 with an MCC casting.
