I've looked all over and can not find reference to the rear main seal design....

Is it an Orig. / Old Style - 2 pc.?

or Late Model - 1 pc.?

All the ZZ4's I have seen all have one piece rear seals. Don
Thank You!

Yes, I did verify what I had thought... it is a 1 piece seal.

see it listed here.

My understanding from other info I've read today, is that all GM / Chevy V-8's from 1986-ON, have the 1 piece rear main seal?
Hoping that you're just curious & didn't blow one already..............
