WJ Swap - Antilock brakes?

I do NOT have antilock brakes on my 1989XJ

Every single WJ in the Junkyard DOES have anti lock brakes.
The owner of the yard says he thinks Anti lock brakes were standard.

Can I use the brake booster and master cylinder from a WJ WITH anti lock brakes on my 1989XJ? My father seems to think there will be 4 break lines coming off the master cylinder if it does have anti lock brakes, making it not work.

You should be able to, any further division of the lines will be done on the ABS unit itself I imagine.
