  1. Love to see a V10 Datsun/Nissan!!!
  2. Weber carbs almost never need a "rebuild". They do get dirty from sitting with modern gas, and sometimes the accelerator pump diaphragm may get torn and need replacing, but other than that, the problems you are having are not likely rebuild worthy. Work the throttle while looking down the carb. If it squirts gas, you are likely ok.
  3. I just did a digital clock delete on a plastic Land Cruiser gauge panel using a two part plastic epoxy from SEM. I am absolutely going to use that product again. Easy to use and sands down nicely without any pinholes.
  4. Assuming this is like most 4x4 front wheel hubs. I do a lot of Toyota axles and have been through this dozens of times, and with varying results. Over the years, I have developed my own method. Sort of. You are supposed to turn the hub as you "set" the bearings with the first torque. This helps get the bearings all the way in, seating themselves against the races. Once the nut is backed off, I don't like the ambiguous instructions, so I have come up with my own 10# torque setting. Since then, I have had only one need re-adjusting. For the lock ring, I torque them on the Toyota axles to 60#. If you are using new bearings, getting this right is all the more important and you'll probably need to re-tighten them after a few hundred miles.
  5. Depends on the cam, porting, carbs, etc. I always ran a 2.5" exhaust with either a turbo muffler or a more expensive and less restrictive Borla "lazy S" muffler. Race cars got a straight through Borla. Hell, I run a 2" exhaust on my 1275cc Sprite.
  6. It depends. Some can go to 89mm or more. They should be measured first. The late M2 blocks are more consistent. The best block for boring large is a Z20 block, but since they are so hard to find now days, L20B blocks are used. Z22 blocks have steam ports in between the 1-2 and 3-4 cylinders that can be accidentally bored into, so having the machine shop offset those bores is crucial.
  7. Cut the flange off, adjust the tubing so it doesn't hit the block, and then weld on a new flange. Someone here sells new two hole flanges, or you can scab one off another application from a wrecking yard, or you could whittle one out of steel. I think muffler shops have a good source for new flanges too, so maybe you shop can get you a new one, or even a pair. All that work and it may be easier to get a different header. Is it actually a header or is it a cast iron manifold?
  8. The dipstick tube on an L motor is a press fit. Getting them out without screwing up the press fit is best done from inside the crankcase, but it sounds like someone already screwed yours up so try pulling it out from the top and seal it with some RTV.
  9. Sometimes using loose terms on a google search helps you zero in on what you need. I searched 1983 Nissan 720 motor mount bushing on google and came up with these results - https://www.nissanpartsdeal.com/oem-nissan-720_pickup-engine_mount.html https://www.summitracing.com/parts/ani-2718/applications/make/nissan/model/720/drivetrain/4wd Do any of these look correct?
  10. How did you find those guys? Their website says nothing about Datsun, only muscle cars.
  11. Good tool to have. A bit noisy though... I use mine about once a week.
  12. Right, comparisons should be made directly, apples to apples. If the springs are soft, then the shocks can feel weak too. On a 4x4, or anything taller than your average truck, I would install a set of Bilstein 5100 series shocks, especially if you're not happy with the ones you just installed. The 5100's are pressurized gas shocks and are built specifically for 4x4's which tend to be taller and have larger tires than 2wd trucks. Remember, the larger (and heavier) the tire, the more un-sprung weight you need to control, hence the firmer shocks. Other companies make similar shocks, like the Rancho RS9000 series, Old Man Emu Nitrocharger and others. Fox makes budget direct replacement shocks that are good too. I would call someone who specializes in Nissan 4x4s and ask their opinion. Calmini does a lot of Nissans and they have been around forever. @banzai510(hainz) - the Ranchos you had were probably RS5000 series and are not gas pressurized, which make them great on the trail but not so awesome on the road.
  13. Too early to pass judgement on the shocks until the tires are balanced. Checking the shocks is as easy as pushing down hard on each corner and see if it bounces back up or rises gently. If it bounces then the shocks are weak. This is the same on the road. Some trucks inherently have a bounce, but that's usually when carrying loads or towing. The front of my Cummins Dodge Ram truck bounces when I am towing, but drives well when not towing. And that's with new Bilsteins.
  14. You don't need the manifold either, but it is nice to not have an adapter that comes loose once a year.
