Re: SER1 80" narrow springs and longer shackles..

The one question I would ask is:  Are the series III plate and the shackle
bolt you tried new or second hand?  New plates are available because of
exactly this problem, both the plates and the shackle bolt wear, eventually
making a loose fit.  Often you will find the eye in a worn plate is oval,
then you need to replace both bolt and shackle.

I would measure the items for you but my Land Rover is 160km away.  The
measurements are easy you just need to add up the dimensions, use the bush
centre length instead of the spring width, add the thickness of the plates,
washer and nut allowing several threads extra.  From memory the shackle
plates are 3/8" hardened plate, the springs are 1 3/4", you need about 3/4"
for the nylok nut plus washer, there is about 1/8" x 2 clearance between
spring and shackle.  You would therefore need a 9/16" UNF high tensile bolt
about 3 1/2" long for each shackle.

You can have them made up if you like, however I used the series III plates
because my 80" plates were far too worn to use, new 80" replacements weren't
available locally and the new series III items were only 5/8" longer than my
originals but most importantly they were easily available.

When I looked into this, I tried a shackle bolt on an SIII plate, and it
was a very loose fit (non-threaded side)..

Finding bots (or re-tapping existing SIII bolts) is not really a
problem..

I've spoken to a local machine-shop, and her reckons he could make me
some shackles, if I can give him a bolt to work from, and some lengths
to work from....
