These are not the same; the Haynes manual for TR-250/TR-6, which use the
same IRS frame for the early models at least, gives the following:
Camber angle 1 degree negative, +_ 1/2 degree
Toe in 0 - 1/16 inch
These are given on the specs page, Chapter 11, Suspension & steering

I would say Yes, any positive camber is excessive, after installing
similar heavy-duty springs on the TR-250 I had 'til recently.
The handling was so bad, it was scary, the rear did not follow the
front of the car on sharp turns, plus the ride resembled that of an
old hay wagon.

The Haynes manual also gives the free length of the rear spring,
10.92 inches. Also the # of working coils, 6 3/4, and rate 349 lb in.
See if yours resemble these specs. I suspect they do not, and would be
a better fit on a later IRS car, such as a '75 or '76 TR-6.
My own solution was to give the `heavy duty' springs to a friend with
the later TR-6, and get his already-sagged stock springs and install them
on the TR-250. This worked for me; just a suggestion, no guarantees, as
the rear frame on the 250 had serious-enough rust & bad weld repair prob-
lems that it may not have been a good candidate to compare to.
