Front control arms

I had the car up on a hoist this past week to check out the front end. It turns out I need the left upper control arm as the ball joint is shot. Intrernet price checks palace the cost at $946 for new and about $400 for a rebuilt unit.
I came across an aftermarket steel part [not aluminum as original ] made by 928 motorsports for $520 per pair.
Has anyone had any experience with this steel control arm? It looks like a good deal to me.

I bought the control arms from 928 motorsports and hope to have them installed next week.I'll also be changing the tie rods cv boots and refurbishing the brakes. Can't wait to get out on the road.

I am interested in how you like them. Not that it is critical, but weigh them to see how they compare as well.

The new control arms weigh 1.2lbs less than original ones. They are a tight fit to get them in but fit well and look great.The car feels new. I had to rebuild an axel, totally rebuild a calliper and refurbish the other three. The new tie rods help to.The studs on the old arms did have to be pressed out (to hard to hammer out. Afraid to mushroom the ends) and pressed in to the new arms.Pictures to follow.

Good information, thanks.

If you have long term usage to report back, good or bad, that could be useful to others as well.

87 Shark - Anything to report back? Interested to hear how they're working out. I'm going to tackle some front suspension items soon as well.
