    Axle swap

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

    Axle swap

    Do you mean the entire rear diff? What are wanting to put in it?
  3. Just click on the link and then you can see it. I don’t do Facebook either.
  4. Valve lash won’t make a difference. It’s pulling oil by the valve seals and guides.
  5. 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.
  6. 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.
  7. 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.
  8. 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.

    mrbigtankers 521

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

    Windshield wiper switch

    Thanks. I figured there was more to it than just swapping switches. Now I just have to find the amp.
  14. I have two 85 ST kingcabs, one has a fixed interval intermittent wiper switch and the other has a variable interval intermittent wiper switch. So the question is can I change out the fixed interval switch for the variable interval switch? Or is there something else I need to change as well?

    Just bought a 521

    For the flywheel bolts, I always used a chain hooked to a transmission bolt on the block and a clutch bolt. Never had a problem.
