Hello, Quick question. would the front and rear springs off a 91 dual cab hilux (ln107) fit onto an 83 dual cab hilux (ln46)

My guess is the later model springs would be much longer than the early model.
Do some measurements, eye to eye, eye to centre pin, centre pin to eye, and measure the arc.
Compare numbers then youll know.

You could always do what is known as RUF(rears up front), which is standard rear springs in the front, with ext shackles.
Then for the rear do what they call IFS rears, which is standard rear springs from an IFS Lux in the rear, with ext shackles.

There is eleventyboggedzillion threads on RUF and IFS rears, have a search around on here and do some reading.
