Front upper spring mount/Upper A-Arm.

I'm wondering if anyone makes any billlet upper spring mounts?

Probably not, but who carries new ones?? As we all know these rust out and can become a PITA... I found some GLobal West upper A-Arms for cheap, so I can prolly swap em out on the new pieces.

The spring seats against them plus they do flex slightly so anything other than rubber or polyurethane would be noisy and dangerous

Find some good stock take-offs or Moog makes them too

^ Yeah.. Stock-ish is completely fine with me. I'd like to retain an isolator on the top. I agree that would be a dumb thing to mount metal to metal.

Moog, eh?? I'll look that up now.

-=EDIT=-
Found em for $55/ea. They're stock alright.. lol.. I know the Foxbodies have the adjustable camber kits with that trick looking upper piece, but again...... metal to metal.. Wondering how it will work to swap out the upper a-arms.

The upper a-arms are attached to a plate that is sandwiched between the upper shock mount and the inner fender - when you remove the shock/spring assembly, it will literally fall out

As far as the upper shock mount that gets rusted out, make sure you buy Moog or get Genuine GM take offs. Anything else fails or the bolts strip out. Sometimes they don't even fit. Unless you're doing some hard core racing, you probably don't need those tubular upper arms. Stock uppers are good enough. You could always go with upper arm poly bushings for increased stiffness.
If you really want better controls arms, buy rear adjustable lowers. At least you will get more performance gains out of the purchase.
That's just my .02

Aren't those AC Delcos? Just making sure since I'm getting new mounts also.

They probably are AC delco. AC Delco is just one supplier to GM for their parts. I'm only saying be sure to get the original factory parts or Moog. I would personally go with the factory parts even though Moog is good. Sometimes the factory parts are actually better. I've used take off upper mounts, I do lots of autocrossing and push the front very hard with Koni's and Strano springs and I've never had a problem with the factory shock mounts or arms.

EDIT: By the way Lizard, nice car. Looks familiar.....
