Was wondering firstly if I need to get new leaf seats to weld to the rear end or if the stock ones will work. Also, I assume I will need new shock plates as well. I've read about the ride height issues that other guys have when going with 5 leafs so I'm going with 4 leafs. I was thinking of using Classic Industries' installation kit and the 4 leaf springs they offer. Anyone use these before? Right now the ride hide is fine on my 69 SS 350. Want to keep it that was but without the squishy rear end.

Thanks!

10 or 12 bolt?

The rearend is 10 bolt posi. Thinking of maybe putting sport springs also. I would prefer to not have my rearend torched/welded on if I can help it, but if I must to do the job right then I will. What about 3 leafs?

The car is pretty much a cruiser - 327 with estimate 300 hp with a TH350 if that helps in the diagnosis. New Monroe shocks as well. I do drive it as much as Ican though more than just weekends.

I don't want to raise or lower the car, it's just squishy, especially when I have people in the back seat.

Wagonman, will contact you when I figure out what I'm doing, thanks!

Thanks guys -

I have just recently got mine on the road and converted from mono to multi, used the same shock plates and bought the shock extenders from Classic. I do not like the ride much, similar to a hay wagon feel every bump on the road. I was looking to see what I can use to give a smoother ride and not feel every bump.

Your rear end already has staggered shocks, but the mono-leaf perch does not have provisions for the bolt head that holds the multi-leaf springs together, so even adapters, have to be adapted. You just need to grind off your old mono spring perches and weld on replacement multi leaf perches. You can buy them new on line at many places here are a few:

Or used wherever you find them (they have no moving parts so they aren't subjected to a lot of wear, just depends upon how surgically precise the removal was.).

No you don't..

Just install 5/16" carriage bolts that you have re-threaded longer and that you have ground off the square from under the head. Install them in your springs and WHACK hell outta them with a 3 pound BFFT and install them!!

Sure, the mono stuff will bend some AND the pads won't fit all that good w/o trimming the lips off their sides, BUT they will do fine just like what's under my car now!!

Thanks Guys for all the help. I ended up going with a set of 4-leaf Eaton springs. The supplied me with all the proper hardware and were very courteous and helpful.

The car rides great and sit about 1/2 to 1 inch higher in the back - looks great. I would suggest Eaton anytime. They asked me alot of questions about the car and what i use it for and the guy gave me the perfect set of springs.
