    Escort lowering block kits fit the back, cut the front coils each whole coil equals approx 1 1/2" of drop.

    This is how I did mine many moons ago before I went down the " Hydraulics " route.

    Cut 3 coils out of the front springs & cut off about half of the bump stop.
    If it has Power steering make sure the steering ram is securley held in place or you will regually ground it out.
    If your using the stock steel wheels, simply fit a pair of 185/65x14 tyres.
    It will sit perfect but mind those pot holes.

    With the rear the easiest way is fit 2" Ford lowering blocks ( wont do too much ).
    Or use a pair of 1" blocks with the 2" kit, the 3" blocks will now just fit with the long U bolts you get in the kit ( getting there ).
    Or make your own 4" blocks using Box section & make your own U bolts from threaded rod ( worked on a friends V8 powered one ).
    The way I did it was by removing the Leaf springs & had them ( lowered ) by Leda, basicly they bend them cold so when you refit them they actually bend the wrong way & drops the car about 4" or so ( thats how I did my 64 PB ).
    On the 71 PC I went further by doing the same & getting the springs bent, but I also fitted 2" lowering blocks aswell.
    I fitted 205/70x14 rear tyres which filled the arches & the car sat level.

    By the time I fitted the hydraulics, to drop the front on the floor I simply removed more coils & the bumpstops alltogether.
    The rear was more tricky,
    To drop it down to the ground I removed 2 or 3 leafs from each spring & fitted 185/65x14 tyres like the front.
    But now the prop was rubbing on the prop tunnel so I had it cut out & raised 2" along the whole length.
    The exhaust was swapped for a PB single system which just cleared enough.

    Hope this helps.
    Just how low do you want to go ?????

    ooh ooh Andy love....

    Was waiting for you to post that....

    One thing Leda are no-more; as we know it anyway - I have no idea where you'd get de-cambered springs done now. Anyone have any ideas...

    Ah haaa Jonny boy.

    " De-cambered "

    Thats the word, I couldnt think of the right word for the life of me :****er:

    So Leda is no more............Just another engineering loss for old Blighty again.

    I know a man called Bubba who lowered his Marina on its belly by removing one leaf & refitted it upside down.
    Home made De-cambered springs.
    Drove like **** mind...................Whod a thought

    Aha, so that's how you did it. Works very well.
