harmonic balancer sbf

[5.0kid]

I bought a project car last summer and it has a 351 windsor in it and I replaced the distributor with a msd tfi distributor and a billet timing pointer but I noticed that the rubber ring on the stock balancer has slipped so I made my own mark and set it back to tdc to get the car running, so my question is I want to buy a new aftermarket balancer but don't know which weight I should buy can I weigh the old one? To reference when buying a new one

351 Windsor non Roller (69-94 ?) Is 28oz. I got a new stock one from autozone under $50 (I think)
