I own an 84 BII that I have kept stock with the exception of the duraspark conversion. Mine has a 4 spd manual that has been rebuilt, I also rebuilt the original 2.8 and replaced the stock carb with a Holley 2bbl. I removed the cat and the air pump, during my rebuild, I made an aluminum plate to block off the air pump port and the mechanical fuel pump port. I had no issues with removing the air pump or the cat. You should be fine towing short distance, it will be sluggish but it is a 2.8l. The biggest concern is overheating, the heads on the 2.8l are very susceptible to cracking if any overheating occurs. Had to replace one head during the rebuild. The 4wd system is good for light duty trails, etc. If you are going to do anything, I would recommend getting an 8.8 rearend with disc brakes from an Explorer and a Dana 35 front from a 91-94 Explorer. This will maintain your manual locking hubs, give your rear disc brakes, both are heavier duty and will allow you to swap in a V8 if the motor ever gives up on you. There are many more options available for these axles than the 7.5" rear and Dana 28 front you have now. The Duraspark conversion is easy and gets rid of the computer and all of the emissions stuff. Good Luck
