broken lower p/s rear shock mount

Ive had several xjs so I knew in advance about replacing the rear shocks
in perparation for adding a lift. Par for the course, I broke all 4 upper bolts even after 2 weeks of pb blaster and heat. Those are fixed, however even though one lower mount nut came off clean, the p/s bolt snapped. Part of the bolt is smooth and that part is still connected to the rear axle mount. It snapped where the threads start, even after 2 weeks of pb blaster and heat.
Ive had the top bolts snap but never the bottom bolts. Does anyone know how to repair this fairly cheap as I only paid $800 for the cherokee. I did do a search but came up empty. Im sure I can have someone remove the axle mount and weld in a new one but that sounds costly.
Thanks in advance

Could you drill and tap what is left and use a grade 8 bolt to hold the shock on?

i cut off the old stud then drilled out the rst of the stud on mine and used a 5/8 bolt and big washer, worked great

drivers side mount

Was thinking about both of those ideas, was looking to see it anyone had suceeded. Thanks for to you both prompt responses and pic, I now have tommorows project.

I just ran into the same thing this weekend and drilled out a hole and used a grade 8 5/8th bolt. We shall see how it holds up but I think it'll be more than fine.

You can buy a replacemant stud at most auto stores for about 5$ for a pair!

i did the same thing and just cut a 1/2 bolt down and beveled, welded it on and put 1 extra washer to compensate for the weld...been 4 years now still holding.
