Does this look right? Im confused

So I know absolutely nothing about suspension, but I consider my Dad a pretty amazing mechanical wizard. We are still trying to get this nightmare of a brake job cleaned up. In the process, Dad noticed these blocks in the suspension. After some examination and 100 questions, we cant seem to figure out if they are serving any purpose or are correct.

I remember the original owner telling me he lowered the front and raised the back a little bit to obtain the specific stance he wanted, but Dad seems to think these blocks on each side of the rear aren't serving any purpose in their specific location. The tires size in the back is 255/45/17.

This picture is of the drivers side of the car, from the back - looking forward. Any help with this issue would be greatly appreciate.

Thanks so much!

Dennis

Yes, doing nothing in that location......now if they were above, they'd lower the car some.

Re: Does this look right? Im confused

I am guessing they center the shock in its travel at ride height. At least one would hope they do...

Thanks for the help. Is there any reason to keep them?

Looks like someone removed the rubber pads and installed the block to make up the space.
Block is thicker than needed, hurts nothing to leave, and if you want originality they'd have to go.

All in all.....up to you.

Re: Does this look right? Im confused

If the car is lowered there is a chance your shocks are going to bottom out in compression without those blocks. I am not saying that is why they are there but there is a chance that is why they were added. They increase the compression travel of the shocks....

Can you ask the previous owner what his logic was?

Re: Does this look right? Im confused

You need a block or rubber pads to fill the gap between the spring and the spring perch. A much thinner block leaving enough room to secure things together is what I would do. Then determine to put over or under the spring to alter the rear height.

Post a pic of the shock at ride height. How much shaft is exposed?

Re: Does this look right? Im confused

Maybe had a multi-leaf rear at 1 time and put in the mono leaf and removed the multi springs?

Re: Does this look right? Im confused

The spring perch looks too shallow for multi-leaf springs. Centering the shock travel seems like a plausibility. Somebody may have been groping at ride height and messed up (I'll be starting my own thread soon!). I don't like the crazy gap between the perch and the shock plate. Those things bend when you torque them to spec! Good picture!

Re: Does this look right? Im confused

Right, it is a mono rear now, but the block appears like a filler for putting a mono leaf spring in a multi leaf rear...

According to the picture above, this is not a multi-leaf rear...too shallow.

Re: Does this look right? Im confused

It's a mono leaf perch with pads removed. The usual problem is the leaf spring only has a locator on the bottom, it can slip in the rubber pads and the axle moves forward. Using a lowering block below like this without pads makes for a more positive location of the axle and makes up for the loss of the pad thickness. I'm against using the rubber or poly spring pads, they are troublesome if you have much horsepower. Those mono-leaf lower plates are thinner steel than a multi leaf set, so tend to bend when overtightened and they position the shock eye lower than a multi leaf plate. This is done because the multi-leaf spring is thicker and the spring plate sits lower.
If you will stay with mono leaf springs, I'd pull the plates, and weld reinforcement bars crosswise left to right to strengthen them and find a thinner aluminum spacer. But it will work fine this way, it just places your shock a bit low but most mono leafs this old are sagging and lower than stock anyway... If you go to a multi-leaf spring, then multi-leaf perches are recommended. If this is a 67, then the only thick multi leaf plates are made by Detroit Speed.
