MGA rear leaf springs

["Rick deOlazarra" <cattail@redshift.com>]

Hello people;
 Leaf spring's broke.  The other's almost straight when the car's at rest.
Need to replace both.  I've been getting indications of springs that have been
over-arched, from one or more suppliers, leading to the rear end raised a
couple inches too high.  Would rather not go through that.  Has anyone
experienced buying and installing correctly arched springs from a
supplier/distributor, and which ones were they?  Thanks for any help.
