Hey Old Timer,
It's coming along. I've made a couple of changes in the past week, like bolting the cab directly to the frame instead of using angle brackets and making a homemade altenator bracket to mount the altenator lower and closer to the engine. In answer to your last question, if you're still thinking of using an S-10 frame. I don't think there'll be too much stress on the front end and bearings with 2" spacers. Off roaders use them all the time with good results. With 2" spacers on each side of the front wheels, it will bring your stance out to almost 60". Along with the 60" rear from a 4X4 S-10, you should be good to go. If you still need to fill out the fenderwell, go with a wider tire.
