No. I only put some tension on the engine just to hold it up as I was dropping the K out from the bottom. I did try to drop the old box out from the bottom, but that was a no go unless I undid the header. At that time, I didn't even think about going from the topside with the engine tilted some by the screw jack. Since I was changing the K out, just left a couple of bolts in it so it would come out with the frame. Once the frame was down, I took the bolts out, pulled the box out, then pulled the frame out. If you decide to go with a new unit, go either with the Borgeson from BAC[ Peter is one of our sponsors on the forum] or Lares like I did. The Lares is new and a direct replacement for the oe unit. However, plus the tech gal told me this, if you have stock exhaust it will have no fitment issues. If you have headers, you're on your own. I did have to thump #3 and #5 tubes. 3 for the box itself, 5 for the coupler. The Borgeson would most likely fit in better since it's smaller than the oe. I would highly recommend you don't have an oe, rebuilt stocker put in. Depending on the source for the unit, you could either get a good one that doesn't leak, but has a dead spot when straight or a leaking POS. Very few companies do a true rebuild. Most just toss a seal or two at it, paint it black, then kick it out the door. They may warranty the unit, but will not reimburse for the labor. Choose wisely.
