Hello All - hoping someone can help me out with an issue regarding suspension height on my 1965 Thunderbird hardtop with AC. I just bought the car and the previous owner had the front end and springs replaced from parts from one of the well known Tbird parts houses. The rear end was very low though and I suspected it needed rear leaf springs. I bought the complete kit from the same parts house and had them installed but made very little difference and the "old parts" looked fairly new-ish, still with stickers on them. The shop thinks the rear isnt so much low as the front end is too high. It does look high but according to the receipts, the last owner did order the correct springs (hardtop with AC). I'm stumped as to where to go with this next before I order new coil springs and get the same thing I have now. Any ideas for me? I can take measurements on mine is someone has a 1965 hardtop that sits correctly. Thanks!

Steven, perhaps a simple way to raise that rear end would be to put adjustable air shocks on the rear... My '59 has them on it, which raises the rear end more and levels it out... Let's see what else others say about this.

Ray - thanks for the reply. I have considered that though the front end seems a little too high. At the local shop they wondered if someone put heavy duty coils on the front although the receipt I have from the previous owner seems to show they should be the standard coils.

Although the receipt shows they are standard shocks, it would certainly not be the first time that someone sent the wrong parts to a customer... I will be interested in hearing what jopizz and others have to say about this problem...

Thunderbirds of that era all have a slight rake to them where they are lower in the back. As Ray mentioned if you want more height in the rear you can install air shocks or invert the spring shackles.

I've also heard that new springs and leafs have a break in period, especially the leafs, it could take up to a year before they settle, I may be wrong, but I have heard that.

Thanks! This is exactly the info I needed. It seems my car is sitting about 1-3/4" too high in the front and about 1/2" too high in the rear. I imagine if I drop the front, the rear will be exactly where it needs to be. I did buy the springs from one of the big Thunderbird parts houses and did call their spring supplier who assures me its unlikely I have the wrong springs or they are made wrong but I can't figure out why its sitting so high in the front? I could order different springs from a different supplier but cutting mine by one inch might be the best option?

I'd try inverting your shackles first. It worked for me.

Inverting the shackles will raise the rear a bit which sounds interesting since these cars sit so low in the rear but it won't do anything for the for the front will it? It looks like the front is sitting sky high now ..
