TRANSMISSION VIN STAMP
I have a 1970 Boss 302 Mustang. I’m
trying to verify or find the VIN number
stamped on the transmission. The trans-
mission is in the car and I have access to
a lift to get under the car. Where do I look
for the number?Dennis Farrari
Denver, ColoradoTypically, the VIN number on the transmission of a
1970 Boss 302 is stamped in the upper-lefthand ear of the
transmission ( lefthand meaning the driver side, of course).fit on the transmission; however, the
opening to attach it to the floorpan
is different. The 1970 floorpan is
rectangular. The 1971 floorpan is oval-
shaped at the front of the opening in
the floor. I have included a picture of
both boots.3-RIVET OR 4-RIVET
BALL JOINTS
I’m currently getting ready to
reinstall the front suspension back
onto my 1970 Boss 302 after a rotis-
serie restoration to MCA concours
specs. I’ve been told by different
people I need 3-rivet and 4-rivet ball
joint–style upper control arms to be
concours correct. Which one is cor-
rect for my application? I do not want
to do it twice. Thanks!

Topeka, KansasThe 1970 Mustang used the D0OZ-
3082-A upper control arm. This uppercontrol arm was the 3-rivet type.
This upper arm was used on all
1970 Mustangs, excluding the Boss- The original finish is bare steel
with a pink paint ID mark at the
ball joint area.
FOUR-SPEED
SHIFTER BOOTS
What is the difference between a
1970 Mustang four-speed lower shift-
er boot and the 1971 Mustang Boss 351
lower shifter boot? Both use the same
Hurst four-speed shifter. There is no
1971 boot available in reproduction.
