At minimum I would need a D44HP but that has the same size shafts as my D30 and marginally stronger balljoints on the knuckles. so i would be looking for a kingpinned 35 ? splined D60...
mabey when i win the lottory.... i might just polish the turd and get some alloy shafts and carry spare hubs/shafts
just run a std 44/9"/60/8.8, etc. out back and put a glider skid on the bottom of it and be done with it. with only 33's i doubt you will be lifted high enough to require a HP for driveshaft angles which could not be handled via a SYE
