Need lower pulleys with a 3 bolt pattern.

[dmarx]

I need to replace the harmonic balancer on my '79 buick turbo engine, The harmonic balancer on the engine has 6 bolt holes for the pulleys. The replacement balancer from Dorman only has 3 bolt holes for the pulleys. Does any one have a lower pulley with 3 bolt holes that the can part with ?
Thanks

Do you have a picture or part number of the balancer?

No I don't have a part number. The balancer is still on the engine. I have the Dorman part number for the balancer, 549-142, but it only has 3 holes for the crank case pulleys.
