Replacement shaft help

Having a hell of a time finding a front shaft for my xj, I'm assuming my application I'm providing is wrong. Its an 89 xj 4.0 auto but I swapped out the 242 for the 231. the shafts I,m getting are almost 2 inches too short. What should I be looking for?

current shaft 31.5 collapsed
34.5 extended

The overall length of the 231 and 242 is nearly the same.

Some Grand Cherokee front drive shafts are longer.

wicked man! thanks for the catalogue pdf. and it seems my options are expanded! Any idea what ideal travel is for a slip yoke?How much useable travel do you need for a lifted rig? My axle is 1.75 inches forward from stock, so the stock shaft was borderline too short anyways. looks llike a 94 grand cherokee v-8 5spd shaft is an option at 32.75" compressed. I'll have to get the warehouse to measure extended and compressed before I bite the bullet.

some reading looks like 1" shaft showing at static ride height, ad 2-1/2" of spline engagement at installed extended
