The 429 CJ/SCJ Starter (C9AF-11001-A) had a solenoid mounted on it with a
heatshield as shown above. Installed view shown below.
This photo shows a closeup of the solenoid heat shield
used on the 429 CJ/SCJ starter. The close proximity of the starter to the
exhaust manifold made this shield necessary to protect the solenoid from
premature failure.
This is a closeup of an original 429 CJ/SCJ Mustang
starter with the C9AF-11001-A part number visible on the housing.
Here is a close-up of the correct starter nose piece
(drive end) with the C9AF part number and the '70 casting date.
This is the needle bearing/cage assembly used in the
C9AF aluminum starter nose housing.
Battery
For 1971, Ford offered both a Group 24 and a 27 battery, but the 429
Mustang/Cougar used only the 27F. A correct Autolite Group 27F Battery is
shown above, as well as an installed view. The battery tray, hold down,
and fender bracket are also shown above. For those wishing to buy the
Autolite 24F Battery cover that fits over the top of a standard battery,
here are the dimensions of the battery you will need and the post hole
locations for the cover to fit;
Battery Shield
According to the Ford MPC, Ford used a battery shield on cars with air
conditioning or high performance engines (Boss 351 and 429 CJ/SCJ). The
purpose of the shield was to deflect engine compartment heat away from the
battery and help provide cooling. In addition, the shield has a curved
edge on the front that acted as an air scoop. There was a hole in the
radiator support which allowed air to pass through and enter this scoop on
the shield allowing air to circulate around the battery (the shield had
stand-offs to keep a constant air gap around the battery to allow the air
to circulate). The part number for this shield (now obsolete) is D0OZ-10A682-A
(service #D0OB). Original battery shields
are extremely rare today and are highly prized detailing
items.
Battery Cables
The correct positive battery cable
is part number D0OZ-14300-A and the negative cable is part number
D0ZF-14301-A. The accompanying photos show the routing. The eyelet on the
negative cable is a ground and attaches under the lower attachment bolt of
the voltage regulator. If you have an original positive cable, take good
care of it. An NOS one recently went for $500 on eBay.Below is the
reproduction set for the 71 429 Mustang sold by Marti Autowerks.

Solenoid
These photos show the C7AF-A solenoid used on the 71 Mustang/Cougar
and installed views with associated wiring. The Junction Block is shown
below.
Spillproof Battery Caps for the Autolite Battery were
available over the counter and were often used on race cars. These are
quite rare today.
