    Put a 350 Turbo trans in my car this past spring. It was a shift kit in it. This past weekend I broke the drivers side rear control arm. I'm not going to replace just one and I'd like to buy a set and have both replaced.

    Any suggestions on where I can get a good set. Original parts group seems to have a good set for sale but their shipping to Canada is over $200.00. Thanks.

    Are you looking for the OEM style boxes arms,or something aftermarket?

    Doesn’t matter really. Whatever will hold up the best at a reasonable price. Thanks

    Sorry to ask, but how did you break it?

    No bother. I put a 350 Turbo trans in this summer that has a shift kit in it. So when I get on it, it can really light them up going into second. I'm guessing the torque snapped it. Must have been weak.

    Ok. I'm was going to replace both rear but yes you make a good point. I'm going to have my mechanic look the car over. Lucky I was only going 5km when the back tire locked up.

    Thanks guys. My mechanic is checking his stock as he believes he has a set from a restoration he started years ago. If he doesn’t have them I’ll Get back to you. Both sets look really good.

    The car doesn’t have that much power. 300 4bbl duel exhaust. As I mentioned before I think my stock arm was twisted by the added torque from the new trans I had installed.

    A stock pair of boxed arms is all you need then.

    Ok. I just don’t want something like this happening again. Had to tow the car less then a kilometre from my home. It only that I’m more concerned about safety. Thanks for your help.

    Looks like rust/rot to me. Your engine doesn't make enough power to destroy arms like that. Those are open arms, not boxed, so they flex some. A set of boxed arms is all you need. like these,

    Personally, I think those are over priced. Find some used ones.

    I would be looking the rest of that chassis over very good,...that frame rail is extremely pitted,..but as Larry mentioned that control failed because its bushing has been MIA for awhile and its been banging around or it was just rotten. Trans had no bearing on its failure

    Just get some open arms for like $40 here off the board and then the weld in plates for $25 and you'll be good to go

    Thanks. Yes it’s been over looked. Had part of the frame re-enforced a month ago. I live in Canada so the car has most likely seen a lot of salt in its day. I’m actually going to get the frame rails boxed this up coming winter. She’s potty there but overall solid.

    Those are the weld in plates for the control arms, you can do the same with some flat sheet and steel tube, but the product drop in plates are easier and look more better
