  1. Yes. Replaced the alternator and no more problem. Internal regulator was bad.
  2. It is factory. I had one break on my 85 and ran it that way until I parked the truck. Probably 100,000 miles or more. Never caused any problems. I parked the truck with 375,000 miles.

    Axle swap

    Is there something wrong with the original or just want a different ratio?

    Do you mean the entire rear diff? What are wanting to put in it?
  5. Just click on the link and then you can see it. I don’t do Facebook either.
  6. Valve lash won’t make a difference. It’s pulling oil by the valve seals and guides.
  7. I take it you mean the complete differential. Yes it will bolt in. I used a ‘78 diff in my ‘70 years ago. Pinion bearing went out. Not sure about the E brake cables mine were not hooked up. I don’t remember what driveshaft you’re using in your set up, I was using a stock 620 driveshaft with my l20b 5-speed, and of course it bolted up with no problem to the ‘78. Of course the one thing that is different is the wheel stud size is bigger on the later trucks than the ‘70. It worked out OK for me because I was running ‘73 front hubs anyway. That 620 rear end is a little wider as well.
  8. The smoking is probably oil getting by the valves. When using the engine to regulate your speed going down hill, it creates vacuum and pulls oil down by the valves.
  9. I put one in my 85 several years ago and it still works great. Only problem I ever noticed is side supports coming loose. Only saw it when I replaced the water pump.
  10. Is the noise coming from the gears? If so, you can just swap the center section as long as the gear ratio is the same. Or swap it and don’t use the 4wd until you find the proper gear set.

    I would love to see pictures of that Alpine. I had one years ago. No 4AGE of course.
  12. Is there something wrong with the factory setup?
  13. Nice work. Turned out great.
  14. Your best bet is to find a parts truck so that you can get everything you need.
