Install the proper 4bolt mount on the plate and install the ax15 crossmember and you'll be good to go . Your crossmember will be 3/4 inch higher than what should be on there . Then you can make a bracket to hold your exhaust up .
Found one at my local yard and installed it in my 89 with a 95 XJ complete 4.0 driveline. Been to 105 but she had more , just not into pressing my luck
