v8 harmonic balancer weight

does anyone know the weight for series 1 xr engine balancer?? i have just bought a lightened flywheel and it has two balancer weights. ones around 20 and the other is 50 odd

i replaced my flywheel late last year with an xtreme lightened cro-mo one and clutch.
is there a small counterweight and a larger one? i used what the instructions said for the cleveland (think it was the small) and this one is left over, it measures a touch under 140mm at the widest point so its for the later v8's
to avoid shadows i had to move the camera down but it makes it look like the weight is 150mm long..

ps, your thread is a bit confusing too, the harmonic balancer goes on the front of the motor, flywheel at the back.
hope ive answered your question correctly
