In Need of 1987 B2000 Harmonic Balancer!!

Im in need of a Harmonic Balancer for an 87 b2000,.. Anyone know a site that might have them? or anyone have one they want to sell?? I cant find one anywhere..

let me know if you can help in any way

Wish I could help but I only have a spare for my 87 b2200.Just curious what is wrong or the issue at hand.Tired I am and just thought I would inquire.

Well I was noticing a vibration at idle since I bought it, but I just thought it was a 4 cylinder thing, well when I was hooking up the tach, as I was testing which wire to use off the coil, I looked down and saw that the pully off the crank was wobbling.. So I pulled the pully and the crank timing gear off.. Found that the key way was worn down and broken.. So I replaced that, put the timing gear back on, got it in time and cranked the truck.. No vibrations.. So when I put the pully back on it was wobbling again.. So that's why I think its the harmonic balancer..

Ha sorry for the long story there
