1975+ 292 inline 6 pulley spacing?

[cell]

Hi guys,

Does anyone have a 292 inline 6 from 1975 or later?

I have a 292 from 1967, and am looking at replacing the harmonic balancer. I have found a source for aftermarket balancers, but they are listed as being for the 292 from 1975 through 1989. I imagine the only difference will be the pulley spacing, so if any of you can snap a quick photo of your '75-'89 balancer, I can figure out if I can use it or not.

thanks!
