Upper Control Arm question-repaired it

[oldcarnut]

Today I pulled the front clip of my 70 RR to start a little work towards the SB clone.  I then began tear down of the suspension to rebuild it,  I know the bushings were worn but it drove pretty good while I worked on other things.  I pulled the UCA's off and got a little surprise.  The bushings had most of the rubber gone and the drivers side bolt was actually making metal to metal contact on the arm.  I posted a pic for show and my questions are:
Can I weld up and rework the worn area and just reuse it?
I'm going to try and find another good used arm first if there is one available somewhere but needed to know what years are the same for the 70 RR?
Maybe tommorrow I'll get to the rest of it and order the parts from Rock Auto unless someone knows any site doing a promotion sale.

If you are concerned, I think Frank Badalson and Roger Gibson are now reproing the upper control arms for 68-70 B bodys.  Don't know what the pricing is or not but thats what I seem to remember.

Here's the info from Frank. Thanks for the feed back.  I'll search for a good used one after trying the weld repair.
UCAM Authentic, stamped steel right and left upper control arms, 1858856 and 1858857.
Arms only..................................................$ 325.00
With 2 ball joints, seals, and 4 bushings..............$ 350.0

A member on here was selling a pair of good used arms for $40 each. Shop around before dumping coin on new ones. If you are cash strapped, yes, you could weld up and rework the hole.

I saw those in another thread but they were for a 72 Charger and I don't think they're the same.  I'll  have to find out if the 70 is the same as 68-69 like most things.  The welding wasn't so much a concern of cash as it was about any stressing of a suspension because of welding but I don't think what little bit I would have to do would be a big factor with it.

If the new bushings press in tight I wouldn't worry about the "divot" unless cosmetics are a concern.

No, they won't work, but the point was that there are for sale ads out there with members trying to make some cash for their projects that can help you with your project. I'm often surprised by how many members of the many web sites I visit that don't check the forum ads before making purchases. BTW, your looking for 66-71 B body or 70-74 E body upper arms. That should expand your search considerably.

I took it to work and weld repaired the UCA and it came out pretty decent.  Posted a few pics.  Just waiting on a few more parts to put all of it back.  Bought all moog except for the poly sway bar bushings and links.

Looks great, nice job!

Very nice job!  Can hardly to tell that it was done upon a quick glance.

Thanks guys  .  Check out these sway bar mounts I took off today.  Both of them looked to be pushed forward .  I hope the new ones I ordered have the frame mounts as well as the bushing replacements.  Originally I was planning on doing the LCA's, Front Strutrods, and Torsion bar bushings later so I could move on to the body modifications but now I'm having second thoughts.  Any ideas what would cause these to bend that much as it seems like it would be more than just the worn UCA's  to do it .  This car only had 103K miles on it.

They probably hit a curb. Where they hang, it would be possible to bash them without damaging anything else.
