oil ser ring ?

Would anyone happen to know where to get or what size/thickness the rings are in a standard 4.0 bore 88 tbird 302so?
Could I use a ring from any 302so or 302ho?
On a visual the so pistons are dished flat tops with no reliefs and a slot drain back oil control ring land. Ho pistons have the dish, valve reliefs and small holes for the oil drain back oil control ring land.
One of my ser rings collapsed in my old 302so and was the reason it was fouling the plug, compression checked ok. My Bronco 302 is fubar and this motor would be good for it with a new ring.

 
  Thanks for any help

think there the same, this is based on my checking PN's for rings/bearings for my 302 that im rebuilding with HO parts. im almost positive the "wear" parts are all the same, just the pistons are different.

That would give me a good option if size it the same. Do you think a dial caliper would be accurate to measure ring thickness? I just got a set of ho pistons, but they shipped them in baggies with 1 box and the skirts(possible ring lands) got banged up. Those pistons were going to be used with gt40p's and the stock t-bird roller cam. Using the flat tops would require the E7's or E6's. What do you think?

 Thanks again,
