Does the 1J's, 2J's and 7M's ISCV's use identical check valves?

I was able to source an ISCV from a 1J for my FFIM; however, it did not include the check valve or rubber grommet. Which ones will work and where can I source it from? I'd prefer a new one since I've heard they are prone to leaks at high boost levels.

I spoke with Jeff over at Champion; and he has the 2J check valve and grommet in stock. Can anyone confirm that these will work on a 1J's intake manifold. If not, where could I ever source a 1J check valve and grommet from?

Thanks.

I have found the answer. I'm posting my findings to help users in the future.

Both the 1JZ and 2JZ use identical grommets and check valves for the ISCV.

25748-88400 Valve, Check List $18.81
90210-25001 Grommet List $1.91

I still can't tell if the check valve is identical to the 7M's http://www.cygnusx1.net/Supra/Library/EPC/291410/catalog.aspx?F=2211&P=2 however, the beginning of the part number is the same.
