First off Barry here is a great post written by another Mod on this board named Philip. It shows you a step by step click by click if you prefer way to post pictures not only on this board but any where on the web.

Second you should change out the spring pockets on your rear end when changing over from a mono-leaf spring to a multi-leaf spring. You can buy new Multi-leaf spring perches from Moser or Currie. I also recommend loosing the stock T-bolts that hold your rear end in place and replace them with U-bolts (or J-bolts if you are going to use a slapper style traction bar). Bolts are available from Competition Engineering (formerly Lakewood) or Detroit Speed Equipment (DSE) who also sell ladder bars, or slapper bars to control rear wheel wind up (ladder bars are a race only part as they will cause suspension bind unlike a four link on the street).

DSE also sells a kit to install a multi leaf spring in a mono perch.

And a compromise that Congress could be proud of, is to replace the mono-leaf with a special three leaf multi-leaf spring (the factory used 5 leaves for high performance cars and a six leaf for racing) sold by J. C. Whitney; that purveyor of fine hot rod merchandise such as fuzzy dice, dashboard Hula girl dolls, wolf whistles and aaahhogah horns. (it is actually made by Eaton and will work as a viable alternative to a weak mono spring and fits in your mono perch)

Global West sells a mono to multi setup which will probably be cheaper than anything made by DSE with equal quality.

Default Re: Leaf springs

will the 3 leaf J.C.Whitney springs lift the car in the rear as much as the 5 leaf springs?

If your mono's are sagging from age yes it will restore it to the stock ride height.

The monoleaf spring is a variable rate spring and the thinner sections of the spring get worked a lot more than the rest of the spring does.

My Nova out on the barn is sitting on the ground now because the springs collapsed with age (the arch reversed on the leaf springs first then the front coils collapsed under the extra load). The Nova has 410,000 miles on it having gone through three engines and two transmissions and seven clutches while my dad owned and drove it. I drove the car into the barn and parked it about twenty years ago when he gave it to me. It hasn't moved an inch since then (all four natural rubber Pirrelli tires have rotted in place and mice have eaten holes in the gum rubber tires because they think it is chewing gum; though the body is still rust free).
