anyone know how to lower the front end of a 69 datsun 1000

take out the leaves, flip a couple and reinstall or blocks... thats the only options apart from getting them re set. 1000 gurus fire away.

how do you block this front leaf setup

Get the spring reset, shorten the bump stops,
after 40 yrs most of them are almost on the stops anyway... ha ha

i think you need to get a service manual, should be in the 1000-1200 manual.

This is my ideas.

method 1
You can take a hacksaw to the rubber blocks that sit underneath the end of the spring pack on the lower control arm. this will lower the car up to about 20mm each side assuming you leave half of the rubber block. Note, you need to leave 'some' (about half) of the rubber otherwise the spring will 'slide' on the rubber and cause friction, which will just be horrible.

method 2
1. remove the spring
2. place on a level surface and measure the height of the spring in the centre.
3. separate the spring leafs buy removing the bolt in the centre. Careful - leafs will want to fly everywhere so use a vice and strap it just in case.
4. start with the longest leaf. place it in a vice so that it looks like a frown (i.e. upside down smile). using a ball-pien hammer, tap the upper surface of the spring within the jaws. you want to hit everywhere, so it looks like theres a little dot at every 1mm spacing. move the leaf within the jaw and work your way from one end to the other.
5. reassemble the spring pack and remeasure.
6. repeat this process for the other leafs until you achieve the desired lowering amount.
7. reinstall the spring.

You might be surprised how quick it is to do this and it will cost you zippo. you should be able to do each leaf in about 10-15 minutes. to raise the spring, just tap on the other side of the leafs.

method 3
remove the spring and take it to a spring manufacturer such as Dumbrell springs in Wallsend NSW. They will charge you a few hundred dollars and will probably just apply method 2.

hope this helps.

Oh yeah, i forgot to add, from my experiece if you replace the bushes (i did with nalothane type) you will get rid of a fair-bit of the sag that Dundee1000 mentioned.

also, watch your suspension travel. I would warn against removing or otherwise reducing the effectiveness of the bump stop. its an important part of any suspension setup. you can shorten it a tad but keep it realistic.
