BJ70 vs HZJ73 Wheelbase differences and Overall Length

[ForealBoreal]

What are the wheelbase lengths on a BJ70 and HZJ73.
Also how much bigger is the HZJ73 for room?

 

[hoser]

SWB is roughly 91"
MWB is roughly 102"

MWB interior is longer by ~11" but rear legroom may not be more (maybe even less) because of seat placement.
