Has anyone ever had to replace the highlighted bracket on a 71Barracuda/Cuda? Looks like they were puddle welded in place at factory. Checked with USAutomotive and they can't find anyone listing the part.
They think I will have to have new one fabricated. Any info from anyone who has had this problem would be appreciated. Cheers.

can guarantee it will fit
and the horn on the top that is tcked to the inner wing won't be right for your car

aussies have them bolted through the inner wing at a strngthend section that welds on top of this horn...

this is the other side

before spending any money you would need to find out if the swivel points for the A arm on an A body are the same dimension front to back as those on an E body. if they are

the main bracket part could be seam welded in

later aussie cars also had 1/4 circle sections welded in as gussets to the sides of this bracket to further support the outer ends as it was dicsovred 3-4 years of australian use tended to make the bracket out ends crack. Thus

and the text from the bulletin
The following is an extract of a Chrysler Australia Service Bulletin dated June 1979.
SUBJECT: Loss of Wheel Alignment – Upper Control Arm Reinforcement

MODEL: All Valiant


To overcome problems of loss of wheel alignment mainly experienced with vehicles operated under severe conditions or unsealed roads a running change adding reinforcement plates to the upper control arm brackets was made in late 1978.

In the event that repeat loss of wheel alignment is experienced and fatigue cracking of the front attachment tab of the upper control arm bracket is noticed, on vehicle manufactured prior to the introduction of the reinforcement plate we recommend that the following corrective action is taken.


Remove the upper control arm from the upper control arm bracket (refer page 2-2-9 of the CL Service Manual).


Weld all existing cracks or failed welds on the upper control arm bracket.


Fabricate two reinforcements as shown in illustration below.


Install reinforcement on both sides of the vehicle and weld as shown in illustration below. Clean up welded area and protect against corrosion using zinc rich primer and under body black.


Reinstall upper control arm using new cam bolts and nuts.


Measure and adjust vehicle height and wheel alignment. Note: Correct torque of the cam bolt nuts to 88 Nm (65 lbs./ft.) is important to prevent loss of wheel alignment as the result of movement of the cam bolts. It may be necessary to tighten the cam bolts using normal spanner then raise the wheels clear off the ground to provide clearance for the application of the torque wrench.



If they prove to be too narrow you could Ask Ray and pentastar parts if he could get a B/E body one made. he has access to a range of cars so should be able to help or ask for unassembled bits of what you see

Cheers Dave999, have had a word with a local engineering shop/ace welder and he is going to make and install a replacement to original specs. He also owns a number of American vehicles so is familiar with there workings.
