I had a hell of a time getting the old one out. That took all of my time. The new one slid in super easy. I couldn't contort(sp?) my damn hand to get the dipstick bolts. Playing around with those took some time also. If I did another one, it would go a lot faster.
I figured the easiest way was to unbolt the cab and jack that ****er up to give me a wide open area to pull the old one out. Those damn tabs kept getting hung up on stuff. It worked out but i'd jack the cab on the next one just for some room.
