    These guys seem to have them, but they are a mid eye, so the ride height will be lowered.

    I was thinking the reverse eye was lowered not the mideye.

    I believe the mid eye are between standard height and reverse eye height.  Both mid eye and reverse eye are lowering springs.

    yeah I guess they have just stopped making the reversed eye 4.5 leaf altogether.

    what exactly are you trying to achieve with rear leaf springs?

    I had their 5 leafs on my old car and thought it rode very well.  What shocks are you using and how old are they?   When you say the removal of the 5th leaf didn’t ride so well, what is the ride like now compared to before?

    Re: did they ever start offering any decent 4.5 rear leaf springs

    Was mainly wondering if they ever started making them again they rode alot better more firm in my other car the 66 . I have Bilstein shocks . I feel like I should not have not cut the front progressive springs I have a new set ordered gonna put them on and line it up and see how it drives before messing with rear. will probably get a set of those mid eye 4.5 springs and it sits to high adjust them with lowering blocks. new engine and 24 inch radiator and coils going in next week or so.

    I have Bilstein shocks  ....some think they are too stiff ...I believe Dwayne cut my front coils too much and they sit to low it never scrubbed before and taking the little 5th leaf off dropped the rear too much. I am not going to mess with rear till I get front like I want it.

    Re: did they ever start offering any decent 4.5 rear leaf springs

    If you want a firmer ride then why are you removing the 5th leaf?  Is it only to lower the car?   If so try lowering blocks and put the extra leaf back in.  I’m not expert on coil springs but I’m guessing a progressive rate spring is design to utilize the complete spring and if you remove some of the coil I would think you can greatly affect how that coil acts.

    Re: did they ever start offering any decent 4.5 rear leaf springs

    I think he has stock 4 leaf springs now and wanted a compromise between then and the 5 leafs.  The 4.5s are such a compromise, and should help reduce spring wrap on hard acceleration as well as a 5 leaf. 

    I'd avoid lowering blocks though.  Spring wrap is bad enough in these cars as it is, even without a lot of power.  Blocks make that condition MUCH worse.

    Re: did they ever start offering any decent 4.5 rear leaf springs

    You know they make coil spring 'isolators' (that go under the front coil springs). They come in different thicknesses. 1/2"...1"...2"
    all the way up to 3 inches.
    Moog makes 'em.........Jegs, Summit has them.
    If you need to raise the front back up a 1/2" or so just put one of these under the springs!
    S'wat I did and some others too.
    Sure cheaper than buying new springs because you cut too much off of them
    Under 20 bux......You'll need a new alignment but....new springs would too.
    Look 'em up

    Re: did they ever start offering any decent 4.5 rear leaf springs

    This is Mustangs Plus new site.

    This is made by Scott Drake, 5 leaf, reverse eye
    And if it’s made by Scott Drake, perhaps you can find at a local shop.

    You may want to look at NPD and call to see if they have a spring that fills your desired ride height.
    Eaton makes their springs.

    I have 90’s vintage Mustangs Plus 5 leaf mid-eye springs.
    Don’t know who made their springs back then.

    Another option is Mike Maier leaf springs.

    Scott Drake = RUN

    With the spotty quality of the rest of their products, no way I'd trust their springs.

    Just my 2 cents, I would go with Eaton Detroit Springs. Call and talk to them- they may have made the original springs for your car.

    Or... You can take your springs to a Blacksmith and have them reset. I did this on mine and am very happy with the result.
