What engine balancer do I have?

[86lxhatch]

Hey all,
I would like to re-use the balancer that came off my 85' 302 crank(OEM). I don't know if it is a 28 oz. or 50 oz. I found the numbers D20E-A1A SDK8 stamped on the balancer. I am going from an automatic to 5 speed tranny and want to save money on this part by reusing it. It still looks good. Also, do you know what flywheel I should be looking for?
I did a google search on the numbers and it didn't give me any answers...

Do 302s from the factory come with 50 oz. in 1985?

50oz imbalance. flywheel 157 tooth 50oz. the change happened late '81 but '82 and up are 50oz.

If the motor is original to the car then it is a 50oz imbalance as skunk said. However, the number D20E-A1A SDK8 that you posted indicate that the part was first designed/used in 1972. D=decade 70s and 2=year. A 72 year model balancer would be 28oz imbalance. So either you have a 28oz motor or the wrong balancer was on your motor.
