4.0 swap pilot bushing?

I have a tf999 auto transmission and am swapping in a 1992 4.0 from an automatic xj.

Do I need a new pilot bushing? If so, does anyone know what size and where I can get it?

I'm swapping the engine this weekend and I just want to make sure I have all ill need.

Anyone know?

If I do need one, I am hoping to order it ASAP so it can get here by this weekend.

Pilot bushings are only used to support the end of the input shaft on a standards trans. You need to make sure flex plate from the motor your swapping in will bolt up the the torque converter of your trans. So no you do not need a pilot bushing. Good luck with your swap.
