Can I swap my 3-bolt rotoflex pinion flange for a 4-bolt flange without worrying about pinion preload and any other differential settings?

sure.
Of course you need a different driveshaft.

What kind of a pain is it to get the drive flange off the third member?

there is kind of a tube in the middle of the rotoflex. This has been fitted with Lochtite so once you´ve removed it you´ve won. When I Did this change on my replacement axle I made something like a puller: a big socket with a piece of drilled, plain steel on top. A screw received a nut and was led through the hole in the steel, then through the socket and then screwed into the rotoflex center. By holding the screw-head with a spanner while turning the nut it shouls come out.
(hope I remember everything correctly)
The rest is straightforward and similar to the 4bolt flange

What size bolt will fit into that centralizing peg?
