Anyone know who makes this?

 

Maybe if you attached a smaller photo? Seriously, a better photo, and pa picture of the shaft end of the arm would help you get a useful answer.

 

Updated photo

 

Again, it would help to see what the shaft looks like.

 

They are similar to but not exactly the same as Hotchkis 1103C.

 

Similar....

Thanks for the replies. Will post pic of the shaft.

 

They might be an older version of the Hotchkis arms.

 

^x2^
I thought same.
Call Hotchkis. 1.877.466.7655

 

Thank you! Will do.

 

I'm guessing -these Hotchkis parts are about 10 years old now give or take. This may give a clue- but take note these control arms are a tall spindle ( B-spindle) upgrade. The steel used in Hotchkis parts are real beefy and heavy compared to whats out there.

 

Just got off the phone with Hotchkis. They confirmed that the arms are theirs and approximately 15 years old. They still support their product and have parts available.
They also indicated that these were in fact the "B-body" arms that were commonly used on "A-bodies" for larger brake applications. Also require a 2nd Gen Camaro outer tie rod end. Super nice people at Hotchkis!
Thanks for all the help!

 

They are great people to work with. I used later GM parts- Z28 1LE rotors, Caprice calipers, B-spindles came from a Buick Estate wagon, tie rod ends from Buick GN. This conversion has had some of articles written about it but since then you have more choices in the aftermarket. I wanted as many GM parts as I could use on the conversion.

 

You're absolutely correct, they are great people! Also, thanks for your input as is extremely helpful. Again, thank you therobski!

 

Yes sir...
