Original rear end may be replaced with another from the same
automobile manufacturer; truck rear end prohibited. Distance
between backing plates may not be changed. Any gear ratio that
fits third-member case or housing permitted. Limited-slip or
ratchet-type rear ends permitted. Reinforcement of spring perch
permitted. Spools permitted only with aftermarket axles.
Aftermarket axles not required for front-wheel-drive vehicles.
Larger brakes may be used. Replacement rear end may be
narrowed or widened to obtain original rear-end width. Bracing or
beefing up the rear-end housing permitted.


Swing axle differential may be replaced with conventional housing;
stock trailing arms must be retained, may be beefed up and
adapted to housing, must retain transverse spring. Must install
Panhard bar. Frame may be notched for driveshaft clearance.
Distance between OEM backing plates and OEM wheelbase must
be maintained. Coil-over shock or four-link adaptations prohibited.
See General Regulations 2:11.


I assume that's on the housing only is the way I read it

FRAME
Frame or subframe must be stock for body used. Subframes on
unibody cars may be joined. Maximum-size material to be used is 2
inches x 3 inches x 1/8-inch. Round tubing may be used to tie front
and rear subframes together and join subframe in straight line
extending through car floor, with floor completely welded to
member.

i don't see the words "beefing up" under " FRAME"

Well there used to be something to that effect. But I haven't read that section in a while.
