Alternator Pulley Shaft Size

[19963.4lsr5]

Will this fit an 80 amp OEM alternator?

I think that is what I have on my 1998.

No it will not. The shafts are different diameters.

I have an 80a that I freshened up and want to do it. However, I never took off the pulley to measure the shaft.

You may find OEM pulley specs looking at the 80a alts. DP electric or whatever they are called may have it listed.
