Default 1988 6.2 Crank Pulley (Help Needed)

Hey guys, my first post here. More to come.

So I just bought a 88 suburban with a unmolested 6.2 in it. The crank pulley is done for and is clacking its way to the grave. I am having trouble finding it online and the major auto retailers (autozone, napa, etc) do not have it and have no clue what I am talking about. I have found similar ones on rockauto (here) and i have a video of what my pulley looks like and Ill post it in a spoiler. Can't seem to manage finding one just like it. Gonna take her off tomorrow after work to get a better look at it and will take some decent pics of it and update the post.

Has anyone here changed one or know anything about where to get one like mine? I've heard they go out quite often, someone made a joke saying to change it every oil change, yea real funny. Even If I can be pointed into the right direction of where to look for a new one, I would thank ya.

Are you looking for the whole Harmonic Balancer or just the pully that bolts to it? Did you try looking on e-bay or Amazon?

Yea I need the belt drive side that bolts to the HB. I couldn't find it on amazon either. Ebay is one I have been cautious about. I've heard some things and stayed away.

You can try Leroy Diesel.com. They make a solid Billet pully for the 6.5 but I do not know if they have one for a 6.2

Part No# 15592128

So I took her off last night and wanted to make sure that was the problem so I.... Uh.. welded the splines together. No it isnt perm and I will not be driving it like this. Just wanted to see If that really was the problem. Im sure the crank is way out of balance now. I still need to find one, preferably not 200+ bucks but well, guess Ill have to fork out the money for it.

I know you do not ebay, but you can get one there a lot cheaper. The one from Leroy Diesel is a upgrade, so it will not crack again like OEM. That is a problem that the 6.2 engines have as you know.

Yea Ebay has always been a blank for me. I going to check out Leroy here in a sec, and see my options for It. The 6.2 Is new to me, only drove It once so far (bought it last weekend). Thanks for help Peko.
