How do you tell if they're cast or steel?

Sadly, the large metal sealing ring is broken, looks like the box got dropped and it cracked. Would it be ok to re-use the old sealing ring with a new o-ring?
Your new rings look to be cast, Yellow paint marks on the edges equals "Off Shore" JUNK!

It's tough to tell cast apart from steel.....I run the Trans Go 700 PHK Pump Rings in EVERY 700/200/4L60E build! Best $8 dollars you will ever spend!

Reuse your old support, Run the shiny side toward the O-Ring.

Re: 700R4 build thread.

Thanks! I've got the transgo unbreakable rings on the way.

I REALLY appreciate the info!

EDIT:

I emailed the seller of my pump kit, asking about whether the rings were steel or cast iron. Here is their reply, which makes me want to laugh and cry at the same time.

Because they are attracted to a magnet I believe they are steel.

The lesson here is to only buy known reputable parts from known reputable sellers.

I'm betting this one had a trans-go spring between the 2nd Acc piston and the separator plate - given the pic below from when I opened it up back in August.

Your above comment didn't soak into my head until after I'd driven out the 2nd Accumulator pin and staked the ball from the Sonnax Pinless kit into the housing. I didn't think it would be a good idea to try and go back, so I went ahead with the Sonnax Pinless piston and the original unbroken spring, as per Sonnax's '94-Later instructions (spring in the Accumulator body, then Piston with dome toward the separator plate). Do you see any issues with that setup?

FWIW, the Trans-Go springs are a tight fit into that Sonnax piston, no wonder they can break.
