Which Leaf Springs to match my Torsion Bars?

You will not need a lowering block with the Hotchkis leaf springs.

I'd go Hotchkis or MP XHD.

Thing is the MP leafs don't have the extra leafs top and bottom next to the front eye to prevent rear end hopping under acceleration AND braking.

My old springs are stock OE 1968 340 Formula S leaf springs. The black ones are Hotchkis leaf springs.

Holy crap those Hotchkis look like they're the way to go.

On a side note: I have researched that getting the back of the car down 2" would make a lot more difference than one would think (actually, doing so makes it handle much better was what I learned), but can I run a 27" tire out back if I go with the Hotchkis or XHD's w/ 2" block?

Thinking about a 255/50R17:
