question about flywheel

I removed a flywheel this afternoon and want to make sure it's correct before I install it on the new motor.

E1ZR6380-AA and has 157 teeth, looks like a 50 oz but has a lot of holes where a lot of metal was removed.
Maybe cut down to a 28 oz?

can anyone tell me what the E1ZR6380-AA is?

My books don't cover '81.

Thanks
Dwight

According to the Mustang forums, that is a 1981-1985 50 oz. wheel for a 5.0 Mustang with a 10" clutch. If it has an additional number stamped into it (something like E6ZR) it is for a 10.5" clutch used from '86-'93.
The pictures on those forums show lots of balance dimples drilled into the weight. One that was well pictured had 13 "holes".
