S13 240sx Q45 diff swap, also Ford 8.8 diff - driveshaft and axle/half-shaft options

S13 w/ '97+ Q45 diff swap for 3.69 ratio.
Pretty sure I got it down, just want someone to check the work.
ALL Q45 diffs (pre and post '97) have a thicker ring gear and a bigger pinion / pinion gear right?

Already have a '95 or '96 J30 diff in the car with 3x2 stubs and stock 3x2 axles.
'97+ Q45 stubs bolt to J30 5-bolt axles? And these axles swap directly into the s13 hubs?
Other option is the pre '97 Q45 stubs w/ z32TT/Q45 6-bolt axles and would need z32 TT hubs right?

And If one was retaining the stock s13 3x2 half shafts and just bolting in the q45 diff could they just pop out the stubs and pop the ones from the J30 in? Just to get the car moving...

I'm actually pretty sure I'm gonna scrap going with the q45 diff because I want a higher numerical gear than 3.69, but would like those questions above answered.

If using a Ford 8.8" diff, what driveshaft do you use? Does the stock one bolt up? Axles/half-shaft options?
